A method for computing the generalized inverse A+ and the associated projections AA+ and A+A for any matrix A is developed It is also shown that the trace of a sequence of approximations to AA+ (or A+A) converges to the rank of A. Finally, examples are given showing the computation of the generalized inverse and rank.
