WebHere is an example (the results come from Matlab and have nothing to do with any implementation of mine): M = 32.7276 -5.0470 -5.3461 -1.7619 -5.0470 10.1665 -5.1195 -2.0058 -5.3461 -5.1195 38.7891 10.4173 1.7619 2.0058 -10.6087 38.5192 M = U S V T (obtained with the command [U S V] = svd (M)) WebWell this is the inverse of this original matrix. This times this will equal the identity matrix. So if this is a, than this is a inverse. And that's all you have to do. And as you could see, this took me half the amount of time, and required a lot less hairy mathematics than when I did it using the adjoint and the cofactors and the determinant.
