Using pdsolove(SyPDE, BIC, numeric), I have to model propagation of two waves , u(x,t) and v(x,t) , in two elastic test rods that are in contact. The problem are boundary conditions at the contact surfaces: values of forces and strain are equal at the first rod right end and at the second rod left end:
D(u)(l_1,t)=D(v)(0,t) and (u)(l_1,t)=(v)(0,t)
Maple can't do that. Should I put in code some transitional Maple expression or function for force and strain, like, for force X:=(delta*x)/l, in order to get this:
Hey, does anyone here know how to program the product Nystrom method for solving integral equations of the second kind? Thanks
suppossed i have a function as following :
where x is belong to (0,Pi/2), I3,I5 is defined to I3^2+I5^2 < .232.
i have ploted some curves of f(x) . As to different I3 and I5, the curve of f(x) have different point of intersection with y=1 function, may one point or two point or three where 0<x<Pi/2.
hi,i am new to this and when i start up maple 12 i get the following error:"Java Virtual Machine Launcher, could not create the java virtual machine".
I have a problem with define(f,multilinear). I want that Maple threats alpha[i,j] as a constant such that f(e, alpha[2, 4]*e)=alpha[2,4] f(e,e). I've added all the alpha[i,j] to the constants, but still, he fails to compute f(e, alpha[2, 4]*e).
It works when I add alpha(i,j) to the constants, but then the rest of my program doesn't work, so it really should be with [,] and not with (,).
I've recently updated to Maple 12 (on Mac OS X.4.11) and am still learning how to use it. A search on Maple FAQs didn't turn up any answers to the following questions.
I am posting it again. I need the plot of W(i+1/2)=1/2*(W(i)+W(i+1))+1/2*sqrt(sagma*t)*g(i) where g(i) is an independent N(0,1) sample. Please some one help. i have attached a file of the plot which I need.

In my 3 D histogram the colums have a 1*1 base, so normally they would be labeled 1,2,3,4,5 on the x and the y axes but instead of this I want to label them 0.25,.05,0.75,1,1.25,1.5 and so on..........
Is there a way to do it?
I created a 3D histogram
with(plots); with(LinearAlgebra); A := [,,,]; matrixplot(A, heights = histogram, labels = [c1, c2, ExpectedProfit], tickmarks = [spacing(2), [seq(i, i = 0 .. 8, 3)], default], axes = normal)
Now I want to assign a colour to each column. When the value is 2 of the Matrix it should be red for example, when it is 3 for example yellow and so on. Later Later I want to expand it to a Matrix with B[n,m]n=10 values...
Thanks alot in advance for your help!
Hi to all,
I am new to maple. I want a maple procedure for the following Boundary values problem.

I installed maple 12 as root user successfully. But sometimes simple command like
1+1 or any command takes a long time to complete. After a long delay maple
displays result. It's happening very often and it's annoying. I'm using Debian
Etch, kernel 2.16.8-custom.
I've a question about "convolution". How can I afford the convolution of different scaled functions?...
In Example: F (2*X/T) in convolution with G ( X/T ) ?
Is this equals to : Int ( F(2*w/T) * G((X-w)/T), w=-infinity.. infinity)?
Am I wrong?...
The particular problem is :
Convolution of ( T*Triangle(2*X/T) ) with ( shah( X/T ) ),
with Shah (x) = Sum( Dirac (x-n), n= - infinity.. infinity).
Thanks for helping!
I am totally new to Maple, therefore the code I submit could be very inefficient. A few comments
help me here:
suppose we have:
how can we find the best values of m and n such that h(x) > 0
one can show that for m = n = 1
h(x) > 0.
one may solve this by first finding the derivative of h(x)
and then solving
solve(diff(h(x),x),[m,n] )> 0
we may assume x > 0
which one is easier to decrypt Vignere of length 6 or 2X2 affine matrix???
