Dear all,
I'm having a trouble with with a matrix Z s.t. A*Z = Identity matrix, given a known A that can be non-invertible. Is there a way to approximate Z?

Dear Gia Quoc Bao Tran , you can use Moor-Penrouse pseudo-inversion of matrice A:
A+ = (A*A)-1A*

Dear Professor,
Thank you. If we take, e.g., B = [1; 2; 0] then Z = B^+ = 0.2*[1 2 0] and BZ = [0.2 0.4 0; 0.4 0.8 0; 0 0 0]. Is this the closest we can get to an identity matrix?

Nowadays computers solve any equations in seconds because they can carry out trillions of calculations per second.
