Detailed Description

BLAS Level 3 API.

The hemm functions perform one of the matrix-matrix operations:

C := alpha*A*B + beta*C if side == HIPBLAS_SIDE_LEFT,
C := alpha*B*A + beta*C if side == HIPBLAS_SIDE_RIGHT,

where alpha and beta are scalars, B and C are m by n matrices, and A is a Hermitian matrix stored as either upper or lower.

• Supported precisions in rocBLAS : c and z.
• Supported precisions in cuBLAS : c and z.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	side	- [hipblasSideMode_t] HIPBLAS_SIDE_LEFT: C := alpha*A*B + beta*C HIPBLAS_SIDE_RIGHT: C := alpha*B*A + beta*C
[in]	uplo	- [hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: A is an upper triangular matrix. HIPBLAS_FILL_MODE_LOWER: A is a lower triangular matrix.
[in]	n	- [int] n specifies the number of rows of B and C. n >= 0.
[in]	k	- [int] n specifies the number of columns of B and C. k >= 0.
[in]	alpha	alpha specifies the scalar alpha. When alpha is zero, then A and B are not referenced.
[in]	AP	- pointer storing matrix A on the GPU. A is m by m if side == HIPBLAS_SIDE_LEFT. A is n by n if side == HIPBLAS_SIDE_RIGHT. Only the upper/lower triangular part is accessed. The imaginary component of the diagonal elements is not used.
[in]	lda	- [int] lda specifies the first dimension of A. If side = HIPBLAS_SIDE_LEFT, lda >= max( 1, m ). Otherwise, lda >= max( 1, n ).
[in]	BP	- pointer storing matrix B on the GPU. Matrix dimension is m by n.
[in]	ldb	- [int] ldb specifies the first dimension of B. ldb >= max( 1, m ).
[in]	beta	beta specifies the scalar beta. When beta is zero, then C does not need to be set before entry.
[in]	CP	- pointer storing matrix C on the GPU. Matrix dimension is m by n.
[in]	ldc	- [int] ldc specifies the first dimension of C. ldc >= max( 1, m ).
