Function rgsl::eigen::symmv_sort

pub fn symmv_sort(
    eval: &mut VectorF64,
    evec: &mut MatrixF64,
    sort_type: EigenSort
) -> Value

This function simultaneously sorts the eigenvalues stored in the vector eval and the corresponding real eigenvectors stored in the columns of the matrix evec into ascending or descending order according to the value of the parameter sort_type
