@Bendesarts It works for me in Maple 16. What error are you getting?

Note that MatrixVectorMultiply(A, B) can be shortened to simply A.B

@Bendesarts Would you please show me an example of it not working? With the above commands, I am able to do diff(gamma(t), t) and simplify(gamma(t)) with no problem.

There is no attached file on your question.

@J4James Sorry, I didn't notice the attached file. I got it now.

What is it that the output doesn't match? Can you show a graph of the alternative?

It's an interesting problem. The simplified form that you got with solve andsubs contains sqrt(s[4]), even though the expressions to be simplified and the side relations are purely polynomial. The simplify-with-side-relations will never introduce sqrt like that. There may be some options though. I haven't been able to get it to work yet, but there may be a way where you change s[4] to s[4]^2.

Thanks for the addition. I had stretched out the computation for pedagogical reasons---to emphasize the linear algebra---thinking that the OP was taking a course in it.

No MaplePrimes 2D math mode, please, because it looks like this:

Generally only real symmetric or Hermitian matrices are classified by the "nature" of their definiteness. Those matrices only have real eigenvalues.

So, the ion is always placed on one of the coordinate axes, right? Then it can be done as three 2d plots: Energy vs. position along the axis, done for each axis.

Mehdi,

Do you mean that you want to do exact computations? Or do you mean that you want Maple to truncate the decimals rather than rounding them?
