Detailed Description

BLAS Level 3 API.

hemmStridedBatched performs a batch of the matrix-matrix operations:

C_i := alpha*A_i*B_i + beta*C_i if side == HIPBLAS_SIDE_LEFT, C_i := alpha*B_i*A_i + beta*C_i if side == HIPBLAS_SIDE_RIGHT,

where alpha and beta are scalars, B_i and C_i are m by n matrices, and A_i is a Hermitian matrix stored as either upper or lower.

Parameters

[in]	handle	[hipblasHandle_t] handle to the hipblas library context queue.
[in]	side	[hipblasSideMode_t] HIPBLAS_SIDE_LEFT: C_i := alpha*A_i*B_i + beta*C_i HIPBLAS_SIDE_RIGHT: C_i := alpha*B_i*A_i + beta*C_i
[in]	uplo	[hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: A_i is an upper triangular matrix HIPBLAS_FILL_MODE_LOWER: A_i is a lower triangular matrix
[in]	m	[int] m specifies the number of rows of B_i and C_i. m >= 0.
[in]	n	[int] n specifies the number of columns of B_i and C_i. n >= 0.
[in]	alpha	alpha specifies the scalar alpha. When alpha is zero then A_i and B_i are not referenced.
[in]	A	device pointer to first matrix A_1 A_i is m by m if side == HIPBLAS_SIDE_LEFT A_i 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_i. if side = HIPBLAS_SIDE_LEFT, lda >= max( 1, m ), otherwise lda >= max( 1, n ).
[in]	strideA	[hipblasStride] stride from the start of one matrix (A_i) and the next one (A_i+1)
[in]	B	device pointer to first matrix B_1 of dimension (ldb, n) on the GPU
[in]	ldb	[int] ldb specifies the first dimension of B_i. if side = HIPBLAS_OP_N, ldb >= max( 1, m ), otherwise ldb >= max( 1, n ).
[in]	strideB	[hipblasStride] stride from the start of one matrix (B_i) and the next one (B_i+1)
[in]	beta	beta specifies the scalar beta. When beta is zero then C need not be set before entry.
[in]	C	device pointer to first matrix C_1 of dimension (ldc, n) on the GPU.
[in]	ldc	[int] ldc specifies the first dimension of C. ldc >= max( 1, m )
[in,out]	strideC	[hipblasStride] stride from the start of one matrix (C_i) and the next one (C_i+1)
[in]	batchCount	[int] number of instances in the batch
