Dear experts, 1. last question: My Matrix M:=Matrix(10,2,[]) has 10 values containing the results f(x) and the second 10 values containing the x values. Now my question is how can I plot these values so f(x) on the y achses and x on the x aches. 2.And: I have a second matrix of the same size and want to plot it into the same graph. How could I do that? Thank you very much in advance !!!!!!

Dear experts, I have calculated a matrix M1 and now I wanted to click the right bottum of my mouse to select "browse" and the export it to excel. Unfortunately I did not find browse. Where did I do a mistake?

Dear experts, I have a matrix with 20 values called M. What do I have to write that maple gives me all 20 values in the result. I mean that Maple shows all 20 values?

Hi there,

it might sound stupid but I wasn't able to program a procedure with

1. peding number of parameters: e.g.

f := proc(a1,a2,...)
....
end proc:

should be good for both f(1,2) as well as f(1,2,3,4,20) and so on.

2. I also wasn't able to program a procedure with an optional parameter:

f := proc(a, opt)
...
end proc:

should be good for f(1) as well as for f(a,"h") etc.

 

I'm working with lengthy computations in Maple right now and I was just wondering whether it it possible to display some kind of "progress bar" after you hit the return button to start the computation.

At least in the form that text is displayed (e.g. "now is a good time to drink your coffee, computation may take a while") BUT that vanishes after the computation is complete.

Hi there,

I try to plot several graphics and print them out as follows:

for i from 1 to n do
  p:=polygonplot(...):
  disply(p);
end for:

but nothing is being diplayed. Doing that just once does the job but I need those plots for large n...

Long story short, running a loop that takes random variables and does various statistical things to them.

The loop has to run about 10^7 times with the final value going into an Array but I cant do that because the Statistical stuff such as CumulativeDistributionFunction takes up so much memory that I end up losing the kernel.

But... Today I came across the gc() command. I put this in at the end of my loop (before the end do), and lo and behold I was using virtually zero memory for the loop. Only what was needed to fill an Array.

 

So Maple and I are not the greatest friends and I need help. I have searched google, this forum and other forums for help to no avail. If somebody would be so kind as to help me with the problems that I am having that would be greatly appreciated.

I think the problems are in the initial and boundary conditions because there are so many recursive statements but I am unsure how to enter these so that I get a favourable result. Without the boundary and initial conditions I do get a general solution.

Dear experts, I defined a certain procedure that I use several times. Is there an option to save it so that I do not have it in each working space? Thanks you a lot!

I would like to use a series of Maple worksheets, written by Professors Malidi Ahamadi and Jean-Jacques Gervais, designed to compute the normal forms of ODEs and PDEs. The code was written for an earlier version of Maple (maybe version 7 or 8) and doesn't run anymore on Maple 13. I would like to make the necessary adaptations to the code to run it on Maple 13. Unfortunately, I am no Maple expert...

When I run the worksheet, the following error message shows:

Dear experts, the results are always displayed in blue. When I type: #StandardDeviation(x) as a comment, you do not see it in the result. when I just write StandardDeviation(R1) he calculates it. But I just want to display StandardDeviation(R1) as a headline of the blue results. How could I do that?

I am trying to do the following sum

with(numtheory):
sum(bigomega(j),j=1..n)

But I get this error message

"Error, invalid input: numtheory:-bigomega expects its 1st argument, x, to be of type integer, but received j."

I have tried

assume(j,'integer');

but this has no effect. I'm a bit puzzled why Bigomega doesn't work in summations as  other Numtheory functions I've used have all worked.

Dear experts, I want to display the results of my Maple Simulation in a new window or pop up. Do you have an idea? Thank you in advance!

Dear experts, I defined a procedure in a simulation that I run in MAPLE. Each time I want to run the simulation I have to click return again and have to wait for some seconds. Is there a more efficient way? Maybe to save the procedure in Maple ? or antother option? Thank you in advance for your help!

Maple 13 help describes at least two ways to invoke classic maple, one, for example, through the Windows start - all programs -> Maple 13 .  But there sure is no classic Maple option there.  Where is Classic Maple?  ..........Edgar
