i have a work on Magic Squares , and i need to rotate or flip them to all 8 possible directions .
but i am confused to find such special commands in maple for doing my purpose !

may you guide me how can i do this programmaticaly ?

Hi all.

I'm a student learning Algebra.

I've been searching everywhere and cannot work out how to plot and analyze a function graphically in Maple.

For example, you can see in this video, There is a point for the Vertex of a parabola on the example

http://www.maplesoft.com/TeacherResource/topic.aspx?m=1&c=1&cha=3&sec=9&top=31

I would like to put things like this on my graph (Vertex, or X-Intercepts, or the intersection of 2 lines)

I can certainly find this information by using Algebra (vertex form, etc) but it would help my understanding to also visualize the functions graphically.

restart;
ode:=diff(y(x), x, x)-y(x)*(a^2*x^(2*n)-1);
dsolve(ode,y(x));

gives

     DESol({diff(_Y(x), x, x)+(-a^2*x^(2*n)+1)*_Y(x)}, {_Y(x)})

as answer. I read the help on DESol, but what does the above actually mean? Where is the solution of the ode? It just returned the ode back to me. Can I consider that Maple did not solve this ode in this case?

from help

"DESol is a data structure to represent the solution of a differential equation. It is to dsolve as RootOf is to solve."

From 1 to 1000, how many time we use "5"?

Hi,

print_result.mw

How could I convert HFloat type number to a number?

My ultimate aim is to print the ouput in a "nicer" wa, like this

printf("Minimum value is: 2.440\n");
printf("x=2.257\n");
printf("y=0.000\n");

and possibly can be written to a file (using writeto).

Thanks,

Hi,

I have been using Mapleprimes for many years. I have asked a lot of questions as well as helped, commented on some posts.

But I always found it a bit difficult to dig up my old posts. So I can have a look what I have asked.

In the "account" page, I can find "Subscriptions",

In the "www.mapleprimes.com/recent/" page, I can find "Your Contributions".

But is there some where, I can dig up ALL my posts (those I have "asked") only?

Thanks,

Hi,

Say I run a procedure, it could take about 3 minutes to run, or maybe hours, or longer.

Is it possible to trigger a sound, like "ding", after it's finished?

I may like to read something while the program is running, but I want to see the results immediately.

It would be nice to have such function.

Also, for procedures that runs for a "long" time, could I get 10 (or 15) minutes sound notice?

Thanks,

casper

Hi,

I wonder if there is a way to achieve this, say I have 4 Maple worksheets,

sheet1.mw

sheet2.mw

sheet3.mw

sheet4.mw

all of them can run seperately. Each of them runs on lots of data, and takes a big chuck of time. I hope to run them one by one. After each file is completed, save (Export) as PDF file, and move on to the next one.

On my own PC, I use Maple X64 windows version. I have never used the command line, but I suppose that will be done in this version, instead of the GUI version?

On the school server, it's Maple X64 linux version. So it's also has the maple command line version as well as the xmaple version.

Thanks,

casper

restart:
seq1:=seq(i,i=1..5);
seq2:=seq(i,i=2..6);
dseq:=seq2-seq1;
seq1:=seq(i,i=1..5);
seq2:=seq(i,i=1..5);
dseq:=seq2-seq1;
seq1:=[seq(i,i=1..5)];
seq2:=[seq(i,i=1..5)];
dseq:=seq2-seq1;

Is that possible to get the differences between two sequences directly? (instead of using a list)

I don't quit understand why the second method would collapse the 0s into just a single value. It's not a set.

Thanks,

casper

Suppose i am trying to do a sequential if command as follows:

seq(`if`(a[i] < b[i], c[i], d[i]), i = 1 .. 10);

now this doesnot evaluate the i's in c[i] and d[i].

please help me with complete evaluation of this statement.

I'd like to try the new Maple IDE

http://www.maplesoft.com/products/toolboxes/IDE/index.aspx

Maple IDE - Integrated Development Environment

Is there a way to obtain a trial version even for a week just to try it out? I do not want to spend all this money then find out it does not work well.

any one here uses this and can recommend it or comment on how well it works? For example, can one run Maple code directly from it and have the code execute in Maple, or must one load the file manually from the editor into Maple to run it each time they make any changes to the code?

I want to sum over several variables at once.

For example, something like

add(add(add(f(k1,k2,k3),k1=range1),k2=range2),k3=range3);

sums over 3 variables. But this can only be done if I know the number of variables in advance. I want to write a code that will sum over m variables, with m being supplied on demand.

Maple can do this for integrals. If I write

int(f(seq(k[i],i=1..m)),[seq(k[i]=range[i],i=1..m)]);

the integral is computed over m variables, for any m.

How can something like this be implemented for summation?
