Pseudo-inverse calculation is time-consuming particularly for large size matrices. However, if you have already known the pseudo-inverse of a particular matrix and want to get the pseudo-inverse of its rank-one submatrices (eliminate one column or row) or super-matrices (append one column or row), than these two small tools can do this much quickly for you.

Please let me know any bugs or your suggestions.
