BLAS Level 3 API.

herk performs one of the matrix-matrix operations for a Hermitian rank-k update

C := alpha*op( A )*op( A )^H + beta*C

where alpha and beta are scalars, op(A) is an n by k matrix, and C is a n x n Hermitian matrix stored as either upper or lower.

op( A ) = A, and A is n by k if transA == rocblas_operation_none
op( A ) = A^H and A is k by n if transA == rocblas_operation_conjugate_transpose

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue.
[in]	uplo	[rocblas_fill] rocblas_fill_upper: C is an upper triangular matrix rocblas_fill_lower: C is a lower triangular matrix
[in]	transA	[rocblas_operation] rocblas_operation_conjugate_transpose: op(A) = A^H rocblas_operation_none: op(A) = A
[in]	n	[rocblas_int] n specifies the number of rows and columns of C. n >= 0.
[in]	k	[rocblas_int] k specifies the number of columns of op(A). k >= 0.
[in]	alpha	alpha specifies the scalar alpha. When alpha is zero then A is not referenced and A need not be set before entry.
[in]	A	pointer storing matrix A on the GPU. Martrix dimension is ( lda, k ) when if transA = rocblas_operation_none, otherwise (lda, n) only the upper/lower triangular part is accessed.
[in]	lda	[rocblas_int] lda specifies the first dimension of A. if transA = rocblas_operation_none, lda >= max( 1, n ), otherwise lda >= max( 1, k ).
[in]	beta	beta specifies the scalar beta. When beta is zero then C need not be set before entry.
[in]	C	pointer storing matrix C on the GPU. The imaginary component of the diagonal elements are not used but are set to zero unless quick return.
[in]	ldc	[rocblas_int] ldc specifies the first dimension of C. ldc >= max( 1, n ).
