I wish to use an array of the size 3000x1000 inorder to calaculate electric fields. Can Maple support such large matrices? The calculations involved in the simulation are of algebraic nature like, addition, subtraction and division.

Is Matlab better in this case?

Basically I am trying to generate equipotential lines abd electric field plot from a given distribution of electric potential.

Many years ago, I played Scrabble competitively. One of the first things a beginner tournament player should do is learn the two-letter word list. Recently, I created a worksheet that tests your knowledge of all the valid two-letter words accepted in official tournament play in North America. The worksheet makes extensive use of the StringTools package which has terrific tools for manipulating words.

The worksheet link is below if you'd like to try it out, and I'll...

Hi guys, can someone tell me how I can get a numerical answer to the following question:

>with(inttrans):

>invlaplace (15/(s³ + 6s² + 15s + 15), s, t)

The answer I receive from entering the above commands is not the numerical answer. I know that the answer should contain sines/cosines/exponentials - how do I get that?

thx

Hi,

I'm relatively new to Maple and was wondering if there was a way to use a do loop to plot a succession of graphs with different colors and legends.
So far I have

for C to 7 do
S := 'S';
S := .7+.1*C;
p || C := plot(R[123], lambda = 5 .. 25, y = 0 .. 1, legend = "S=0.7+(0.1*C)")
end do ;

display(p1,p2,p3,p4,p5,p6,p7);

But I can't figure out how to actually get the legend to update or to assign a new color to each line.

Could you tell me how to build a maplet in Maple 16

What is the differences between Maple and Matlab? Which should I use?

What is the lastest version of Maple and Matlab ?

How do I look for a 9 digit pi-sequence within decimal places of the EULER e  and find the position of that string.

2,71828182..............314159265..........

      123.....................x

can someone show me screen shot how to do this??

thanks so much

I'm new user in maple programming and I trying to constuct a for loop but I taken this Error on my program! here is my program:

There is a flaw (bug) in the DEplot routine.  If you load the plottools package before using DEplot with the arrows=line option, the DEplot routine tries to use the line definition from the plottools package.  A worksheet illustrating this problem is below.

This is a follow-up question to my last-name evaluation question a few days ago.

Well, I thought I had got it, but look at this trivial example involving records:

r:=Record(p1=parm1,p2=parm2);

r:-p2;

         parm2

parm2:=0;

r:-p2;

        0

eval(r);

Dear All,

Im trying to model a rigid body, hanging from a string. In the end I have a system of 5 Equations of Motion and with all the Initial conditions I use dsolve. It gives me the error 

Error, (in dsolve/numeric/DAE/isolate) is not linear

I know the system is not lnear but that should be not a problem. One strange thing I notice is that Maple adds these dots in some equations: (the one after 15 but please see original file)

15.*cos(`ϕz`(t...

In the folders Maple 16: there is a file named MapleToolbox_Window.exe. What can I do with it?

The Strengths of maple 16 is Algebra. What the other application of maple ?

For a while I haven't received notifications about updates to answers and comments from MaplePrimes. Is that due to the recent problem with fake messages from Maple?
