Solving B=inv(X)*A*X

[Denis Crete]

Hello,
I want to solve for X

B = inv(X)*A*X

where A and B are given symmetric complex matrices.

I understand that there are solutions for only special cases, but as 
they originate from a physical problem, I know there should be a 
solution (although certainly approximate...)

I could not figure out what function of Scilab I should use and how. I 
tried "balanc", "bdiag", "equil", "spec"; but none seems to be appropriate.
Thank you very much in advance.
