[Lapack] Pseudo-inverse of complex matrix

I do not have time. I can give it for extra credit in my reading class if a 
student is interested.
If I do not contact you, no one is interested. Sorry. If I come back to you, 
this will in one / two weeks with a code.
It would be useful to have an example of creation of pseudoinverse using 
LAPACK, indeed.
We have the question quite often.

Dear Julien,

Thanks very much for your response. I have already looked at the forum and also 
registered and posted a question. The discussion in the form for REAL matrix, 
however it is useful, but I need for COMPLEX matrix. I would be grateful if you 
can help or if you can connect me to someone you think that he knows these

You can have a look at our forum. There are a few discussions on how to compute 
the pseudoinverse using LAPACK.
See for example

Dear Sir/Madam,

My name is Nawras Hamdan, I am a PhD student. I would like to ask you if you 
have the routine (in FORTRAN 77) which does the Pseudo-inverse of rectangular 
matrix (n*m); n>=m, which is known by the Moore Penrose Pseudoinverse.

I appreciat your time.
