  Mat* mat_q)

Finds eigenvalues of symmetric tridiagonal matrices.

Documentation

Finds eigenvalues of symmetric tridiagonal matrices. The matrix is represented by a pair of vectors a (diag entries) and b (sub-diag and super-diag entries). Eigenvalues in a on return, and eigenvectors in mat_q, if this one is not NULL.
