SVD Only With Matrix of Full Rank?

[parisse]

Writing a good implementation of SVD takes time and it's not really part of a CAS. Inside Xcas, it is not required because LAPACK is called. On the calc, you will hopefully have my homemade quick and dirty implementation in a future firmware. If one can convince me that there is a real need for a state of the art implementation on a calc, I might improve this implementation later, otherwise it will stay like this, unless Han or someone else writes a user program for that.
