Greetings all,
I'm looking for a way to do symbolic matrix algebra, that is to state a
symbol is a matrix of some dimension and have mathematica treat it as
such, i.e. resolve products, sums, products with scalars etc. I'll give
an example to what I mean, suppose A is a n by m matrix and B is a m by l
matrix than:
C = A B
should define C as a n by l matrix and:
C = A + B
should return an error message concerning inappropriate dimensions.
Further if m11,m12,m21,m22, q11,q12,q21,q22 are all matrices with
appropriate dimensions and:
m := {{m11,m12},{m21,m22}}
q := {{q11,q12},{q21,q22}}
than m q should produce the correct result (different from q m).
Is there any way to do that, or any package that can help me?
Guy
