The Matrix Cookbook is available online at: http://orion.uwaterloo.ca/~hwolkowi/matrixcookbook.pdf
It is simply a collection of matrix properties which are proved elsewhere. I have done enough matrix calculus to know a basic approach (very similar to the derivatives for indexed tensors in Maxima) if it has to be implemented. The single entry matrix is sort of a generalization of the Kronecker delta function used in matrix calculus.
