NAMEHPL_dlange - Compute ||A||.SYNOPSIS#include "hpl.h"double HPL_dlange( const HPL_T_NORM NORM, const int M, const int N, const double * A, const int LDA ); DESCRIPTIONHPL_dlange returns the value of the one norm, or the infinity norm, or the element of largest absolute value of a matrix A:max(abs(A(i,j))) when NORM = HPL_NORM_A, norm1(A), when NORM = HPL_NORM_1, normI(A), when NORM = HPL_NORM_I, where norm1 denotes the one norm of a matrix (maximum column sum) and normI denotes the infinity norm of a matrix (maximum row sum). Note that max(abs(A(i,j))) is not a matrix norm. ARGUMENTS
EXAMPLE#include "hpl.h"int main(int argc, char *argv[])
