Detailed Description

BLAS Level 2 API.

gemvBatched 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, ..., batchCount.

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]alphadevice pointer or host pointer to scalar alpha.
[in]Adevice array of device pointers storing each matrix A_i.
[in]lda[int] specifies the leading dimension of each matrix A_i.
[in]xdevice array of device pointers storing each vector x_i.
[in]incx[int] specifies the increment for the elements of each vector x_i.
[in]betadevice pointer or host pointer to scalar beta.
[in,out]ydevice 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
