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

 

Hello,

suppose I have two (or more) different matrices, not necessarily with the same number of rows but with the same number of columns.

I know I can use RowSpace in the LinearAlgebra package to obtain the RowSpace of one matrix, but I would like to consider the intersection. Is that possible?

(In fact, I am particularly interested in the vectors in that intersection that only take the values zero and one, or in other words: all non-zero entries of which are equal. Would there be a trick for that?)

 

Many thanks!

 

Please help me to Solve the following problem?

3^2^3*3^2^2=?

Hello out there,

Hopefully somebody can help me.

I have a little function lets say: n:= l -> sqrt((C1*l^2)/(l^2-C2^2)+(C3*l^2)/(l^2-C4^2)+(C5*l^2)/(l^2-C6^2)+(C7*l^2)/(l^2-C8^2)+(C9*l^2)/(l^2-C10^2)+1);

(it is a sellmeier equation for the refractive index of quartz

and Maple can also plot it for me:

plot (n(l), l=350...1600)

But now I need the data on which the plot is based to be exported to excel or origin.

I tried the following code...... un := [0, 0, 0, 0]: un[1] := tanh(k)*tanh(k*n): for i from 2 to 6 do uns[i-1] := eval(un[i-1], t = s): und[i-1] := diff(uns[i-1], s): unp[i-1] := eval(uns[i-1], n = n+1): unm[i-1] := eval(uns[i-1], n = n-1): un[i] := un[i-1]-(int((und[i-1]-(1-uns[i-1])^2)(unp[i-1]-unm[i-1]), s = 0 .. t)): end do:
Dear Experts, I am sorry for theis basic questions but I don´t succeed in solving it. I have to matrix A and B with just one column each and 10 values each. So together 20 values. The 10 values of matrix A I want to plot in a graph (the points shoudl be joined to a lign) and the second matrix B also, but I the same graph. Dou you know a solution for that? Thanks a lot!

hello, i just wanted to know how to find the equation of the tangent line for f(x)=x^4-x^3 at the point x=1.2.  what code would be used?  thank you very much in advance.

Dear experts, I have to optimize a function f with two variables x and y --> f(x,y). The function is not differentiable! Does somebody of you know a link where I could find an algorithmen (the best would be a generic algorithmen) to solve this multivariat optimization problem? Thank you a lot in advance!
