Detailed Description

BLAS Level 3 API.

gemm_strided_batched performs one of the strided batched matrix-matrix operations

C_i = alpha*op( A_i )*op( B_i ) + beta*C_i, for i = 1, ..., batch_count.

where op( X ) is one of

op( X ) = X      or
op( X ) = X**T   or
op( X ) = X**H,

alpha and beta are scalars, and A, B and C are strided batched matrices, with op( A ) an m by k by batch_count strided_batched matrix, op( B ) an k by n by batch_count strided_batched matrix and C an m by n by batch_count strided_batched matrix.

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue.
[in]	transA	[rocblas_operation] specifies the form of op( A )
[in]	transB	[rocblas_operation] specifies the form of op( B )
[in]	m	[rocblas_int] matrix dimention m.
[in]	n	[rocblas_int] matrix dimention n.
[in]	k	[rocblas_int] matrix dimention k.
[in]	alpha	device pointer or host pointer specifying the scalar alpha.
[in]	A	device pointer pointing to the first matrix A_1.
[in]	lda	[rocblas_int] specifies the leading dimension of each A_i.
[in]	stride_a	[rocblas_stride] stride from the start of one A_i matrix to the next A_(i + 1).
[in]	B	device pointer pointing to the first matrix B_1.
[in]	ldb	[rocblas_int] specifies the leading dimension of each B_i.
[in]	stride_b	[rocblas_stride] stride from the start of one B_i matrix to the next B_(i + 1).
[in]	beta	device pointer or host pointer specifying the scalar beta.
[in,out]	C	device pointer pointing to the first matrix C_1.
[in]	ldc	[rocblas_int] specifies the leading dimension of each C_i.
[in]	stride_c	[rocblas_stride] stride from the start of one C_i matrix to the next C_(i + 1).
[in]	batch_count	[rocblas_int] number of gemm operatons in the batch
