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,
Yves

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
