integer(kind(hipblas_status_success)) function hipblassrotmbatched_ (handle, n, x, incx, y, incy, param, batchcount)
 

Detailed Description

BLAS Level 1 API.

The rotmBatched functions apply the modified Givens rotation matrix defined by param_i to batched vectors x_i and y_i, for i = 1, ..., batchCount.

  • Supported precisions in rocBLAS : s and d.
  • 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 the x and y 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_1.
[in]incy- [int] specifies the increment between elements of each y_i.
[in]param- device array of device vectors of five elements defining the rotation. param can ONLY be stored on the device for the batched version of this function.
  • param[0] = flag
  • param[1] = H11
  • param[2] = H21
  • param[3] = H12
  • param[4] = H22 The flag parameter defines the form of H:
  • flag = -1 => H = ( H11 H12 H21 H22 )
  • flag = 0 => H = ( 1.0 H12 H21 1.0 )
  • flag = 1 => H = ( H11 1.0 -1.0 H22 )
  • flag = -2 => H = ( 1.0 0.0 0.0 1.0 )
[in]batchCount- [int] the number of x and y arrays, that is, the number of batches.
