how can i import data from an excel spreadsheet into maple10? (please don't tell me i can only to it with maple11). cheers, jake

I'm trying to find Eigen vectors and values for 50x50 matrices (and larger) that are very sparse (at least 80-85% zeros). Using the Eigenvectors function [ (v, e) := Eigenvectors(L) ] function is prohibitively slow, but it seems there must be some way to speed things up by taking advantage of the sparse quality of the matrices. Thoughts?
