integer(kind(hipblas_status_success)) function hipblassrotbatched_ (handle, n, x, incx, y, incy, c, s, batchcount)
 

Detailed Description

BLAS Level 1 API.

The rotBatched functions apply the Givens rotation matrix defined by c=cos(alpha) and s=sin(alpha) to batched vectors x_i and y_i, for i = 1, ..., batchCount. Scalars c and s can be stored in either host or device memory. The location is specified by calling hipblasSetPointerMode.

  • Supported precisions in rocBLAS : s, d, sc, and dz.
  • Supported precisions in cuBLAS : No support.
Parameters
[in]handle- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]n- [int] number of elements in each x_i and y_i vectors.
[in,out]x- device array of device pointers storing each vector x_i.
[in]incx- [int] specifies the increment between elements of each x_i.
[in,out]y- device array of device pointers storing each vector y_i.
[in]incy- [int] specifies the increment between elements of each y_i.
[in]c- device pointer or host pointer to the scalar cosine component of the rotation matrix.
[in]s- device pointer or host pointer to the scalar sine component of the rotation matrix.
[in]batchCount- [int] the number of x and y arrays, that is, the number of batches.
