Thanks for your suggestion, Chuck. The equation arises in the substraction
of two harmonic potentials V and V':
V' = 1/2 x^t * A^(-1) * x
V= 1/2 x^t * B^(-1) * x
V'-V = 1/2 x^t * ( A^(-1) - B^(-1) ) * x = 1/2 x^t * Z^(-1) * x
A is the covariance matrix of the coordinates x in a molecular dynam

Dear Numpy users,
I have to solve for Z in the following equation Z^(-1) = A^(-1) - B^(-1),
where A and B are covariance matrices with zero determinant.
I have never used pseudoinverse matrixes, could anybody please point to me
any cautions I have to take when solving this equation for Z? The bru
