Detailed Description
BLAS Level 2 API.
The gerStridedBatched, geruStridedBatched, and gercStridedBatched functions perform the matrix-vector operations:
A_i := A_i + alpha*x_i*y_i**T, OR A_i := A_i + alpha*x_i*y_i**H for gerc
where (A_i, x_i, y_i) is the i-th instance of the batch, alpha is a scalar, 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, andz. - Supported precisions in cuBLAS : No support.
- Parameters
-
[in] handle - [hipblasHandle_t] handle to the hipBLAS library context queue. [in] m - [int] the number of rows of each matrix A_i. [in] n - [int] the number of columns of each matrix A_i. [in] alpha device pointer or host pointer to scalar alpha. [in] x - device pointer to the first vector (x_1) in the batch. [in] incx - [int] specifies the increments for the elements of each vector x_i. [in] stridex - [hipblasStride] stride from the start of one vector (x_i) to the next one (x_i+1). There are no restrictions placed on stridex. However, the user should ensure that stridex is of an appropriate size. For a typical case, this means stridex >= m * incx. [in,out] y - device pointer to the first vector (y_1) in the batch. [in] incy - [int] specifies the increment for the elements of each vector y_i. [in] stridey - [hipblasStride] stride from the start of one vector (y_i) to the next one (y_i+1). There are no restrictions placed on stridey. However, the user should ensure that stridey is of an appropriate size. For a typical case, this means stridey >= n * incy. [in,out] AP - device pointer to the first matrix (A_1) in the batch. [in] lda - [int] specifies the leading dimension of each A_i. [in] strideA - [hipblasStride] stride from the start of one matrix (A_i) to the next one (A_i+1) [in] batchCount - [int] number of instances in the batch.
