Add power method for FISTA initialization in MATLAB #438

Closed AnderBiguri closed 7 months ago

AnderBiguri commented 1 year ago

Fistas hyperparameter should approximate the larges eigenvalue of A, that can be estimated using the power method.

As default, make FISTA compute this, even if its slow.
