integer(kind(rocblas_status_success)) function	rocsolver_slange_ (handle, norm_type, m, n, a, lda, norm)

Detailed Description

The LANGE functions compute the norm of a general m-by-n matrix A.

The norm computed is specified by norm_type as follows:

• rocsolver_norm_type_one: the 1-norm (maximum column sum),
• rocsolver_norm_type_frobenius: the Frobenius norm (square root of sum of squares),
• rocsolver_norm_type_infinity: the infinity-norm (maximum row sum), or
• rocsolver_norm_type_max: the maximum absolute value of any element.

Parameters

[in]	handle	- rocblas_handle.
[in]	norm_type	- rocsolver_norm_type. Specifies the type of norm to compute.
[in]	m	- rocblas_int. m >= 0. The number of rows of the matrix A.
[in]	n	- rocblas_int. n >= 0. The number of columns of the matrix A.
[in]	A	- pointer to type. Array on the GPU of dimension lda*n. The m-by-n matrix A.
[in]	lda	- rocblas_int. lda >= m. The leading dimension of A.
[out]	norm	- pointer to real type. Scalar on the GPU. The computed norm of the matrix A.
