NAME

lis_array_matvec_ns - calculate the matrix vector product

SYNOPSIS

subroutine lis_array_matvec_ns(LIS_INTEGER m, LIS_INTEGER n, LIS_SCALAR a(), LIS_INTEGER lda, LIS_SCALAR x(), LIS_SCALAR y(), LIS_INTEGER op, LIS_INTEGER ierr);

DESCRIPTION

Calculate the matrix-vector product Ax, where matrix $fIA is not square.

INPUT

m, n: The size of the matrix and vectors
a: The array that stores matrix A of size m * n
x: The array that stores vector x of size n
y: The array that stores vector y of size m
op

LIS_INS_VALUE: y = Ax
LIS_SUB_VALUE: y = y - Ax

OUTPUT

y: y
