lanhb Interface

public interface lanhb

LANHB returns the value of the one norm, or the Frobenius norm, or the infinity norm, or the element of largest absolute value of an n by n hermitian band matrix A, with k super-diagonals.


Functions

public function clanhb(norm, uplo, n, k, ab, ldab, work)

Arguments

Type IntentOptional Attributes Name
character(len=1), intent(in) :: norm
