I am trying to see that two square matrices are same or not in Maple. So I am subtracting one from other and expecting to see a 0 matrix of the same size.
But instead of returning a 0 matrix or some other result, it outputs a string "ee". Does
anyone know what "ee" means?

I am trying to calculate the eigenvalues of the matrix dFxdU (see file attached) and Maple is giving me the message
"Error, (in content/polynom) general case of floats not handled"
This is weird as dFxdU is just a simplified form of dFdU derived earlier in the maplesheet and when I try to
get the eigenvalues of dFdU, it does it fine.
how can we ask maple to assign output of a "solve" command to it's unknown parameter that system solves it, not just displaying it,
and then sorts the answer in terms of one of the indice parameters.
I am developing a code with maple, summing up some elements of a 4th-order matrix like this
for i to 3 do
for j to 3 do
for k to 3 do
for l to 3 do
S[i, j, k, l] := delta[i, j] + delta[k, l]
sum(sum('S[1, 1, k, l]*A[k, l]', 'l' = 1 .. 3), 'k' = 1 .. 3);
But after execution, I get this error:
Error, (in tools/add) bad index into Matrix
"A" and "delta" are 3 by 3 matrices.
Please help me come up with a solution.
How can I Reverse a Fibonacci number and find the numbers between a range 20 and 20000 tia sal2
I've been able to figure out how to get the next fibonacci number in a
sequence given just one number using the floor command see below
x := 987.23
What I'm trying to figure out is:
1) floor doesn't take into account decimals and I would like to
2) I would like to be able to find the fibonacci numbers in reverse
between the range of 20 to 20,000
I am trying to model reflectivity data at a Mn-doped GaAs interface and hence I need to create a Kramers-Kronig Transform to determine the depth-dependent complex value of the index of refraction at specific beam energies. The integral I am trying to solve is the following:
f(omega) = P(2/(Pi)*(∫)^(infinity)(u*f(u))/(u^(2) - omega^(2))du),
I want to shade the region bounded by the curves x^2 and x^3 from x=0..1. Could you please help me with this. Thanks in advance!!
I am using Maple 13 for applications of Integratin. I want to plot region bounded by y=x^2 and line x=1. How can I do this in Maple? Thanks in advance!!
we know that:
X(n+1) =Xn - f(x_n)/f^\prime(x_n)
Now I am using the following commands for showing the 2nd order convergence of the above method:
> f(a) :=0:
> A := taylor(f(x), x = a, 4);
> B := taylor((D(f))(x), x = a, 4);
> C := series(e[n]-A/(D(f))(x), x = a, 3);
> simplify(subs(x-a = e[n], %));
it does not cancel e_n
I know there must be a better way of doint it. Can you please tell me?
I am a sheer beginner of Maple and have a very basic question. I want to poste a question on this board. But before that, I can not find a way to copy and paste the Maple command into this question form. Maple command can be copied into Microsoft Word as rich text, but that can not be copied into this question form. Could somebody tell me how to do it?
I would like to make a 3d plot of the equation:

How can I display the "summary of a matrix)" (1000*1000* Type:matrix etc)?
Thanks a lot

here is my problem.
I solve a non-linear first order DE using numerical method but then I need to know when the first derivative equals 0, and i don't know how to get this derivative because dsolve only gives me the fonction and not derivative...
thank you for your help
