Detailed Description

BLAS Level 2 API.

gemv_strided_batched performs 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, ..., batch_count.

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue.
[in]	transA	[rocblas_operation] indicates whether matrices A_i are tranposed (conjugated) or not
[in]	m	[rocblas_int] number of rows of matrices A_i
[in]	n	[rocblas_int] number of columns of matrices A_i
[in]	alpha	device pointer or host pointer to scalar alpha.
[in]	A	device pointer to the first matrix (A_1) in the batch.
[in]	lda	[rocblas_int] specifies the leading dimension of matrices A_i.
[in]	strideA	[rocblas_stride] stride from the start of one matrix (A_i) and the next one (A_i+1)
[in]	x	device pointer to the first vector (x_1) in the batch.
[in]	incx	[rocblas_int] specifies the increment for the elements of vectors x_i.
[in]	stridex	[rocblas_stride] stride from the start of one vector (x_i) and the next one (x_i+1). There are no restrictions placed on stride_x, however the user should take care to ensure that stride_x is of appropriate size. When trans equals rocblas_operation_none this typically means stride_x >= n * incx, otherwise stride_x >= m * incx.
[in]	beta	device pointer or host pointer to scalar beta.
[in,out]	y	device pointer to the first vector (y_1) in the batch.
[in]	incy	[rocblas_int] specifies the increment for the elements of vectors y_i.
[in]	stridey	[rocblas_stride] stride from the start of one vector (y_i) and the next one (y_i+1). There are no restrictions placed on stride_y, however the user should take care to ensure that stride_y is of appropriate size. When trans equals rocblas_operation_none this typically means stride_y >= m * incy, otherwise stride_y >= n * incy. stridey should be non zero.
[in]	batch_count	[rocblas_int] number of instances in the batch
