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

[Geoffrey Zhu]

Good afternoon, everyone.

I was trying to use lstsq() in scipy.linalg. The prototype looks like
the following:


def lstsq(a, b, cond=None, overwrite_a=0, overwrite_b=0)

cond is said to be used to determine effective rank of a, but it does
not have any further explanation.

Can anyone help me understand what exactly does cond do or where can I
find some more information on this?

Thanks,
Geoffrey
