I am using arpack (the dsdrv1 driver) to iteratively solve the eigenvalue problem
Ax = λx
I am interested in the first m eigenvectors, and I have very good initial approximations for these vectors, so I would like to use my m starting vectors as an initial guess. However, http://www.caam.rice.edu/software/ARPACK/UG/node29.html, which is fine if I only want one eigenvector, but doesn't help if I want more than one.
Does anyone know if arpack will let me use my m initial guesses as starting vectors?
