You can use the OPLinearAlgebra package (http://library.wolfram.com/database/MathSource/4271/) to solve this type of noncommutative algebra problem. -- Steve Luttrell West Malvern, UK "K=E4rger Luise" <Luise.Kaerger at dlr.de> wrote in message news:b05qir$29b$1 at smc.vnet.net... > > 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! > Luise K=E4rger > > > >
