Comment(by antoine.levitt):

 Sorry, should have been clearer - v0 only specifies one eigenvector, I
 want to provide information about all of them, ie a N x k array. But
 actually I see from ARPACK that RESID is an array of size N, and I'm not
 sure it even is the starting lanczos vector. So I'm confused - unless I'm
 mistaken, there doesn't seem to be any way to input all the information I
 have to ARPACK, but there's nothing scipy can do about that.
