I have a large section of code which comes down to one single value  which is different each time you execute the section due to a

random component.  I want find a simple way I can loop the complete section of code and get the output 1, output 2, output 3 etc etc

without having to go in and put [ i , j ] on every single variable. I can do it manually by just start in the begining and press

enter all the way , write down the result and move the cursor to the begining again and start all over again but it is very time consuming.

Hello, I know (more or less) how to obtain the Lie symmetry generators of an ode, but how can I do symmetry analysis (finding the classical symmetries, canonical coordinates, reducing the system) on systems of nonlinear first order ode's? Regards, Nijso

I'm running Maple 11.02 on an intel mac. I can no longer access the help menu search function or access any help topics for that matter. Also, if I hover over the 'help' pulldown menu, I get the spinning pizza of death. Reluctantly, the pulldown menu works but I still can't access anything other than a description of maple help. Thanks for any comments, Court Ashbaugh

Hello all,

 

I am sure that there is probably a simple way of doing this, but I can't figure out how. I want to take n sets. Say 2 for the moment: {a,b}, {c,d} and I want to output all the possible n-tuples (n=2) with 1 element from each set. So: [a,c],[c,a],[a,d],[d,a],[b,c].[c,b],[b,d],[d,b].

 

Does anyone know how I might be able to do this?

Thanks, S

Hello,

i'm solving an expression with the result being a range of the type RealRange.

e.g. RealRange(Open(-1.345464), Open(4.5343535))

How can i substract the max element Open(4.5343535) as real from that range.

Many thanks,

Remco

Hello,

 

this is probably a silly problem but I really didn't find any command for it.

Suppose I have a matrix and I want to remove some rows and columns to consider a smaller matrix within it. Is there a nice way to do it?  This is what I came up with:

restart;with(LinearAlgebra);

 

A := Matrix(3, 3, [[1, 2, 3], [4, 5, 6], [7, 8, 9]]);

 

temp := <(Column(A, 2)| Column(A, 3))>; result := <Row(temp, 2), Row(temp, 3))>;

 

Surely there is a better way to do this?

hi all,

i am quite an unexperience user so the solution to my problem might be obvious to you... i googled for a while and couldn't find anything regarding this matter.  i just want all my plots with maple to use the exponential notation on the y-axis. from what i've observed maple does that when values are on the E-6 regime or smaller, greater numbers are just written out which looks just ridiculous (e.g. .0005 -  i want 5x10^E-4). so is there a way to fix this, set some parameter that would force maple to use the exponential notation from earlier on?

Dear all,

I have used Maple to solve a system of equations. The result involves the variable _S01. Does that denote any (real?) number? What's the difference between _S01 and _Z01?

Thanks in advance

I need to create a magic square of order n=4 using a Matrix.

I have tried many linear equations system. Got me nowhere so far.

Hello! I have a problem in Maple 11 when I try to plot some functions in log log scales. It seems that maple doesn't calculate enough points for low x values because it draws curves with elbows even if they are differentiable. And the curves have very weird comportement for a sum of exponential... I tried to do it mannually (takin the log of the function and replace x by 10^x) but it's no better. It would certainly be clearer if you could see what I am talking about: is there a way I could attach my workwheet (or a screen shot) to the message? Thanks

I told maple to evaluate "limit (cos(1/x) , x =0, right)" and got the result -1..1  Does this mean that the limit evaluates to the interval [-1,1]?  If so, I am not sure that is what I wanted because the limit must be defined about a point.  If maple is calling an auxillary routine to let me know, hey there is no limit, but at least it is bounded by [-1,1], then I guess that is fine, except it would be nice to know that.  Or am I just missing something all together?

I'm having a problem with the palettes on Maple 12. Some of the fonts for the symbols are small, while others are large. For example, my integral symbol is about size 12 font, while my definite integral symbol is roughly size 18 font. Any suggestions on a fix? I'm running Maple 12 academic version on a Macbook Pro with Leopard. Here's a screenshot so you can see what it looks like. The font is way too big, any way I can make it smaller? http://i224.photobucket.com/albums/dd177/wifflestheevil/Picture2-1.png

Hi,

Two quick questions:

1. How do I permanently delete a class from Maple TA, i.e. so I won't be able to restore it?

2. If I have created a class that has a parent class. How do I remove the parent class dependency.

Thanks

Colin

Hi,

I have created a some assignments in one class and wish to move/copy them to another class. How can I do this?

My class structure is:

• Class 1
  • Child class 1
• Class 2

I want to move assignments (not just the question banks) from child class 1 to class 2.

Cheers

Colin

I have a small problem.
I'd like to plot 2 functions in a graph and be able to hide a function for a particular part of the graph.

The functions are:

f:=t->3*t-t^2 and g:=t->2*t
When i plot these functions, I would like to hide the function f(t) for f(t)<1 and I'd like to hide g(t) for g(t)>1.

How can this be accomplished?

Thanks in advance!
