Hi.

I need to work with low-rank matrices represented as the outer product of tall-skinny matrices. Specifically, I need to cover these cases: - Symmetric positive-definite: X*X' - Symmetric indefinite: X*C*X' - Non-symmetric: X*Y' (or maybe X*C*Y')

This could be added by extending MATLRC (allowing A to be NULL). If you agree I could create a pull request. If you prefer to keep MATLRC as it is now, I could add this to SLEPc.
