Public Member Functions
integer(kind(hipblas_status_success)) function	hipblassgerbatched_ (handle, m, n, alpha, x, incx, y, incy, ap, lda, batchcount)

Detailed Description

BLAS Level 2 API.

The gerBatched, geruBatched, and gercBatched functions perform a batch of the matrix-vector operations:

A := A + alpha*x*y**T , OR
A := A + alpha*x*y**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, and z.
• 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 array of device pointers storing each vector x_i.
[in]	incx	- [int] specifies the increment for the elements of each vector x_i.
[in]	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,out]	AP	- device array of device pointers storing each matrix A_i.
[in]	lda	- [int] specifies the leading dimension of each A_i.
[in]	batchCount	- [int] number of instances in the batch.
