I am trying to write my own svd function to use the "dgesvd" method from
lapack, but my problem is that I cannot find the "dgesvd" method from this
import "from numpy.linalg import lapack_lite".
Do I have to install lapack on my system(Ubuntu 13.04 64-bit)? I want to get
the same results as MATLAB 2011b which is why I am trying to write a slightly
different svd function than the function from "numpy.linalg.svd".
I would appreciate your help, Thank you.
