Dear Yves,

My problem is small matrix.
So, it can be solved by your advice.
Thank you for your information. 

Best Regards Tetsuo

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

Best regards,
