Why doesn't Maple provide enough white space when user reaches end of document ? As you can see below, I have reached almost to the end of the page. I believe the default process would be to bring the cursor to eye-level (middle of the screen). Now in this case, I have to hit RETURN enough times to bring the cursor to my eye level.

 

Anyone else find this as an issue ?

 

 


Dear Community,

Entering a long line in 1D mode breaks at the right window bounday. How could I prevent this? I would like the entered line stay just as one, single, long line extending over the window boundary and I would like to use the bottom window scroll bar to view it. BTW it also does not appear, so how could I invoke it? I use Maple2016. I have neither found any information about this in the help, nor in the documentation.

Also is there a possibility to split the IDE screen vertically, as e.g. in Visual Studio? Looking at long programs this feature is very useful.

tx in advance,

best regards

The purpose of this post is to review how well-designed Maple 2017 GUI is for a Microsoft surface pro 4 tablet touch screen with windows 10 pro (64-bit) and to determine the performance of Maple 2017 on my tablet which has a m3 CPU with a 0.9 GHZ base frequency and 4 GB RAM.

First, my experience is that 4 GB of RAM is far from enough. Under heavy load I have had problems before on other software with 4 GB of RAM. 68 % of my RAM and 41% of the CPU is already gone by simply running Maple and my web browser at the same time before I have even instructed Maple to do any calculations.

 

I think a tablet with at least 8 GB of RAM would be preferred. If you only want to use Maple as an expensive calculator then you would most likely not even need 4 GB of RAM. I find that the surface pro 4 to be overpriced for the hardware it provides. I think eve windows 10 tablet http://eve-tech.com/ with up to 16 GB of RAM and with a much cheaper price looks much more promising than the Microsoft surface pro 4. When I use the surface pro 4 with word 2016 and the reference manager zotero word plugin I sometime notice a trailing line when I sweep up or down in a document with a lot of references which I suspect is because of the low amount of RAM. When I played with Maple 2017 on my surface pro I noticed the same trailing line which again indicates to me that there is not enough RAM. However, I am not certain that low RAM is the cause of such problem.  

Secondly, I managed to increase the size of the Maple icons under the File, Edit etc. menu so now they have a perfect size for a touch screen tablet. Very cool!

 

However, as you can see words in the text menu File, Edit etc. are way too small for a touch screen tablet. There is a lot of room to the right so the words could easily be increased in size. I am also a missing a menu item called maplet where you can attach your own maplets for easy access. It appears that Maple 2017 GUI has not been designed with a touch screen tablet in mind. I wish the words in the text menu File, Edit etc. would have increased when I increased the size of the icons. The text and icons in the sidebar are also way too small for a touch screen tablet. The name of the open tabs is also to small and x that you tap on to close the worksheet is also to small. It is almost impossible to close a worksheet because the x is so small. 

I thinks there are ways in windows 10 to increase the text size in the menus but I have only been able to increase the text size and icon size for all software at the same time. Since, Maple is more or less the only software that I have where the menu text is too small this is not an optimal solution.   

The table of content for Maple help files also has too small text as seen in the below picture. However, the biggest problem is not the small words it is the row spacing of the table of content. Some of the words appear almost to be on top of each other. I think the row spacing need to be increased. The text within the help files itself displays beautifully and is in the perfect size.   

 

Another problem is that when you swipe up or down on the touch screen you dont go up or down in the maple document. You just highlight text as seen in the picture below. This needs to be fixed. Highlighting should be done by a long tap on the screen as in word 2017 on a touch screen devices.

 

 

The norm today might be to use Maple on a desktop computer or on a laptop but I am convinced that in the future touch screen tablet will become more and more powerful making them an excellent computers to run Maple on because they are so light and portable. I think Maplesoft must have this in mind when they design the GUI.

Now to test the performance of Maple 2017 on my tablet I decided to generate 1 000 000 random number and see how long it takes. Since I dont have a benchmark it becomes very hard to comment on how fast maple 2017 is on my tablet but I am hoping that someone can run the same code on their machine and comment on this post so we can get a benchmark.        

time(rand()$1000000)

Maple 2017 claims that running such code took about 50 seconds on my tablet however when I timed it with a stop watch it only took around 30 seconds hence I am a bit confused as to where the 20 seconds difference comes from?  

 

I have the following expression:

expand((((o * (((h * h - h * v) * (a * h - a * v) * h * h * h * h * a * a * h - h * h * h * a * a * h * o * (h * h - h * v) * (a * h - a * v)) * a * a * h * h * h * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * (a * h - a * o) * (h * h - h * v) * (h - v)) * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * a * a * h * h * h * h * h * ((v * (a * h - a * v) * h * h * h * a * a * h - h * a * a * h * (h * h - h * v) * v * (a * h - a * v)) * a * a * h * h * h * h * h - h * a * a * h * h * h * h * a * a * h * (a * h - a * o) * (v * h * h * h - h * (h * h - h * v) * v))) * h * a * a * h * h * a * a * h * a * a * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * a * a * h * h * h * h * h * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h * o * (((a * h - a * v) * h * a * a * h - a * a * h * o * (a * h - a * v)) * a * a * h * h - a * a * h * h * a * a * h * (a * h - a * o) * (h - v))) * h * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * a * a * h * h * h * h * h * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h * h * a * a * h * h * a * a * h * a * a * h * h * (o * (v * (a * h - a * v) * h * h * h * a * a * h - h * a * a * h * (h * h - h * v) * v * (a * h - a * v)) * a * a * h * h * h * h * h - h * a * a * h * h * h * h * a * a * h * (a * h - a * o) * (v * v * h * h * h - h * (h * h - h * v) * v * v))) );

When I tun it through the Maple GUI I get this result:

-2*a^23*h^40*o*v^2+2*a^23*h^40*v^3

This is also what Mathematica gives me. However, if I run it through the Maple command line I get this result:

-a^77*h^97*o*v^2+a^77*h^97*v^3-a^23*h^40*o*v^2+a^23*h^40*v^3

Why are the results different?

If I go to the menu under file and open.  Or similarily CRTL-o opens the file query dialog box. 

Can I do this crtl-o programmatically?

Why would firewalls cause issues with connecting to the maple kernel if the CAS is entirely self contained (as ive been told before on this forum)

While debugging something unrelated to Maple, I noticed in Windows task manager that the process

C:\Program Files\Maple 2016\jre\bin

had a Memory(Private Working Set) of 2,251,088K - roughly 10x the memory footprint of any other running process.

Is this normal?

Not a real issue for me (machine has 16G ram) - but it just *looks* wrong

In case it matters I'm running Maple 2016.1 on Win7, 64bit

I have a gensym routine (gensym = generate symbol) which appends Chinese characters to some base symbols to create 'new' symbols.  This works well on Windows, Mac and tty maple.  But I get all square boxes in the linux GUI.

I know the fonts exist as, on the same machine, it works in tty.  But I have no idea how to tell the GUI to go and use those fonts.  Nor why it isn't.

Amusingly, if I try to paste something from the GUI as MapleMath here on Primes, in the 'paste' box, it shows just fine, but then it says it is invalid Maple.

For example, from the GUI I see

but the same thing in TTY is

(x三0不 + x三1下)^(-M)

and I just did cut-and-paste of the same thing.  By this I mean that I took that output with boxes above, put it into a terminal window, re-copied that, pasted it in here, and voila!

So clearly the issue is with the GUI, and only on linux (Ubuntu 16.04).

I'm writing an algorithm that takes a while and I'd like to print status messages periodically. I typically use the command line interface, and this is no problem. I just do a printf whenever I need.

However, some people who will use this code prefer to use the GUI, and I've found that the GUI tends to buffer the output from printf, printing 20-30 printf statements in clumps instead of as they're called. Is there any remedy for this?

How do I set from Maple GUI how much memory from my 4GB RAM and how much CPU time can Maple use before it is shut down?Thank you Jan

Hello
There is some kind of strange behaviour with copying/pasting maple code from IDE to some text editor. Namely, the code collapses into one long line in text editor. Is it OK with Maple IDE?

I have produded a 3D plot where I have used the graphic's lighting->user GUI to set the light color, direction, and ambient lighting to my liking.

 

I would like to save the lighting parameters so that I can reproduce the identical lighting in other plots.  I see no way of reading off the lighting parameters from the GUI.  I tried to "lprint(myplot)" to see if it contains that information but apparently it doesn't.

So my question is: Is there a way to retrieve the lighting parameters from a 3D plot?

Is there a way of increasing the spacing between the maple input and output?

Thanks

How do I export a procedure written inside the GUI (i.e. Document mode) into an external file format that is directly supported by a read of a package module?

Every export format I tried requires post editting by a text editor to "fix-it".  And it seems most export options drop the comment text (i.e. text after a #).

Thanks.

Hello,

I'm trying to evaluate an integral numerically on a unix system with the command line version of maple (version 16). For some entered parameters the integral evaluates quickly but for others it never seems to be able to complete the computation.

Moreover, when running the files, which are .mpl files, via the GUI all integrals are evaluated with ease.

So far I have been unable to find why some integrals and not others are evaluated when submitted via the command line version.
