Hi
I'm fairly new to python and Scipy.
I need to solve overdeteremined least squares A * x = b with b having a known
covariance matrix V.
I've previously used Matlab's lscov function
http://www.mathworks.com/access/helpdesk/help/techdoc/ref/lscov.html
and as a learning exercise, I wrote a low level version of this using the
cholesky, qr, solve, svd functions from scipy.linalg. (I had a peek at lscov.m
for help).
My question is:
Can I do this more directly with an existing scipy function?
cheers Eleanor
