Dear Sir or Madam,
I'm trying to solve quite extensive matrix equations in symbolic notation
with Mathematica and have problems with getting symbolic results.
---
The problem can be shortly described as follows:
simple example: From equation A B == C with the kown matrices A and C i
would like to get a result like B = A^(-1) C (and not all the matrix
elements of B).
another example: By using the function 'Solve(A+B==C, {B11,B12,B21,B22})'
with A, B and C being 2x2-matrices I would prefer to indicate only matrix
{B} as the unknown variable instead of writing all the matrix elements {B11,
B12, B21, B22} (which gets quite painful if you have matrices of higher
order).

Thanks a lot for your help!
