integer(kind(hipblas_status_success)) function	hipblassgemvbatched_ (handle, trans, m, n, alpha, ap, lda, x, incx, beta, y, incy, batchcount)

Detailed Description

BLAS Level 2 API.

The gemvBatched functions perform a batch of matrix-vector operations:

y_i := alpha*A_i*x_i    + beta*y_i,   or
y_i := alpha*A_i**T*x_i + beta*y_i,   or
y_i := alpha*A_i**H*x_i + beta*y_i,

where (A_i, x_i, y_i) is the i-th instance of the batch, alpha and beta are scalars, x_i and y_i are vectors, and A_i is an m by n matrix, for i = 1, ..., batchCount.

• 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]	trans	- [hipblasOperation_t] indicates whether matrices A_i are tranposed (conjugated) or not.
[in]	m	- [int] number of rows of each matrix A_i.
[in]	n	- [int] number of columns of each matrix A_i.
[in]	alpha	- device pointer or host pointer to scalar alpha.
[in]	AP	- device array of device pointers storing each matrix A_i.
[in]	lda	- [int] specifies the leading dimension of each matrix A_i.
[in]	x	- device array of device pointers storing each vector x_i.
[in]	incx	- [int] specifies the increment for the elements of each vector x_i.
[in]	beta	- device pointer or host pointer to scalar beta.
[in,out]	y	- device array of device pointers storing each vector y_i.
[in]	incy	- [int] specifies the increment for the elements of each vector y_i.
[in]	batchCount	- [int] number of instances in the batch.
