qr_cholesky Module Procedure

module procedure qr_cholesky module subroutine qr_cholesky(matrix_A, matrix_B, settings, omega, vr)

Solves the eigenvalue problem by rewriting it to a standard form through splitting of the B-matrix.

Warning

Throws an error if matrix_A or matrix_B is not a square matrix.
