Deat Tetsuo,

If you mean to calculate the pseudo-inverse of a dense matrix, no, there is no specific function for that, but of course it can be done quite easilly computing the inverse of the product of the transpose of your matrix with the matrix itself.

For large sparse systems, this is more complexe ... and is not available either.

Best regards,

Dear GetFEM++ Project

I want to calculate pseudo-inverse matrix by gmm.
Is there any method to calculate pseudo-inverse matrix in gmm?
Thank you.

Best Regard Tetsuo
