| integer(kind(rocblas_status_success)) function | rocblas_srotm_batched_ (handle, n, x, incx, y, incy, param, batch_count) |
Detailed Description
BLAS Level 1 API.
The rotm_batched functions apply the modified Givens rotation matrix defined by param_i to batched vectors x_i and y_i, for i = 1, ..., batch_count.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] n - [rocblas_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 - [rocblas_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 - [rocblas_int] specifies the increment between elements of each y_i. [in] param - device array of device vectors of five elements defining the rotation. 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 )
param can only be stored on the device for the batched version of this function.[in] batch_count - [rocblas_int] the number of x and y arrays, that is, the number of batches.
