EigenVe(M) = Eigenvectors of square matrix M:
Returns a matrix whose columns are eigenvectors of the n by n matrix M. The eigenvectors are sorted in ascending order of their eigenvalues. The method used is from Samuelson PA Proc Nat'l Acad Sci USA. 1943 Dec; 29(11):393-397.
This function can have a problem of determining all eigenvectors when some of the eigenvalues are equal. A message "Not all eigenvectors found" is displayed in this case. Try EigenVe2(M).
