[SciPy-user] cond in lstsq(a, b, cond=None, overwrite_a=0, overwrite_b=0)

[dmitrey]

It uses LAPACK xGELSS routine (I guess prefix is 'D'), so you'd better 
contact LAPACK developers.
BTW you could call the xGELSS routines from OpenOpt framework (see LLSP 
class), but w/o "cond" argument.
Regards, D.
