Hello. I am trying to do a question on inverses of matrices, and I have chosen the fill in the blacks method. I want to produce a matrix for students to enter their answers in. I can get it to produce a matrix with the answers in but when I try and make the answers into blanks it does not work. Does anyone know how to do this? Thanks, nj.

Hi,  assume i have a list

m:=[1,5,3];

My (to the core reduced) problem is:
I want to write a procedure that generates  the sequence containing the listname  together with its elements:

m1,m5,m3

my try:

p:=proc(L::list)
`L`||(op(L));
 end proc;

This doesn't work (illegal use of a formal parameter).

What to do ?

 

 

 

Hi,

want to solve this equation for t  but getting 'Solutions may be lost' error.

eq3 := exp(-1/k*t)*k/(1+k^2)+(-cos(t)*k+sin(t))/(1+k^2);

solve(eq3=0, t);

Solutions maybe lost.

Is this too much for the symbolic engine? Does anyone know of a technique to solve this type of equation?

Appreciated.

Does anyone here know of any Maple code (public, or in the Maple Library, or on www.mapleapps.com, etc) that implements alpha-beta pruning?

I would like to see some examples of how this can be implemented and used in Maple, and possibly learn from it.

How to export worksheet to the HTML format programmatically? And how to export Maple output as GIF or other graphic format programmatically?

I'm seeing some curious behaviour when I use maple to produce MathML for my TA questions. What I want to do is generate the first few terms of a sequence, followed by "...". I've managed to achieve this in Maple, but it's the conversion to MathML that is causing trouble. I've pasted the code below, showing what I'm trying to do. Maple TA code: $W1=maple("printf(MathML:-ExportPresentation( [seq('ln'(2*3^i),i=0..3),`...`] ))");

How do I find for which t is the following equation true?

 

I went to a particular website where I downloaded Maple programs in .txt files.

If I open the files and cut and paste the .txt into a Maple worksheet,

a > is inserted at the start of every line. It would take forever to delete each of these

>'s from the start of each line in a program with 500 lines.  Someone suggested that I put the command

read C:\\filename.txt

into my Maple worksheet. But, this - and many variations, with and without single quotes, file extensions, etc. - does not work.

Any suggestions?

I changed my code to multi-threaded type. but my run time increased! and my CPU usage became 65-70%.I think I made a mistake in programming.
but i have a different question too. I read a paper that said: "when you use a matrix or array instead of single integer in maple, your run time will be badly increase, because your total CPU usage will decrease! i't a result of delay in writing matrix element in ram and as CPU has no command to process and is waiting for data from RAM"
i want to know if it is correct or not.

Hello everyone! First, I have to say, that I am very new to Maple, so excuse my silly questions and please explain carefully ;-) I have a very simple problem: I'd like to solve a linear system, but it doesn't work. It's quite large, i.e. so large, that I did not try to use it by hand and thought: let my computer do it! Here are the two possibilities that I tried: 1. with(LinearAlgebra);

I want to add some information to an existing help page within maple.  Can I do it?

 

I like the access to colors and pen size at the top of the drawing canvas.  But when I re-open a file that has a canvas, all the pen work reverts to the smallest width.  I tried opening the same worksheet in version 11 and the width of the pen was preserved; so the information must be in the file.  When I change the width of lines and arrows, that change is saved.

 

I am on a OS X 10.5.  Is this a bug or a feature?

Concrete example: Suppose I have two (2 x 2) matrices that have entries as operators or other non-commutative object.

In the following example Maple treats the entries like numbers:

with(linalg);

R:=matrix(2,2,[R11,R12,R21,R22]);

X:=matrix(2,2,[A,B,C,D]);

Res:=multiply(R,X);

How can I ensure that these are not commuted like ordinary numbers?

The second part of the question, is how I can also prevent arbitrary application of associativity if I so choose.
