integer(kind(hipblas_status_success)) function	hipblassdgmmbatched_ (handle, side, m, n, ap, lda, x, incx, cp, ldc, batchcount)

Detailed Description

BLAS Level 3 API.

The dgmmBatched functions perform one of the batched matrix-matrix operations:

C_i = A_i * diag(x_i) for i = 0, 1, ... batchCount-1 if side == HIPBLAS_SIDE_RIGHT
C_i = diag(x_i) * A_i for i = 0, 1, ... batchCount-1 if side == HIPBLAS_SIDE_LEFT

where C_i and A_i are m by n dimensional matrices, diag(x_i) is a diagonal matrix and x_i is vector of dimension n if side == HIPBLAS_SIDE_RIGHT and dimension m if side == HIPBLAS_SIDE_LEFT.

• Supported precisions in rocBLAS : s, d, c, and z.
• Supported precisions in cuBLAS : No support.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	side	- [hipblasSideMode_t] specifies the side of diag(x).
[in]	m	- [int] matrix dimension m.
[in]	n	- [int] matrix dimension n.
[in]	AP	- device array of device pointers storing each matrix A_i on the GPU. Each A_i is of dimension ( lda, n ).
[in]	lda	- [int] specifies the leading dimension of A_i.
[in]	x	- device array of device pointers storing each vector x_i on the GPU. Each x_i is of dimension n if side == HIPBLAS_SIDE_RIGHT and dimension m if side == HIPBLAS_SIDE_LEFT.
[in]	incx	- [int] specifies the increment between values of x_i.
[in,out]	CP	- device array of device pointers storing each matrix C_i on the GPU. Each C_i is of dimension ( ldc, n ).
[in]	ldc	- [int] specifies the leading dimension of C_i.
[in]	batchCount	- [int] number of instances in the batch.
