| integer(kind(rocblas_status_success)) function | rocblas_zrotg_batched_ (handle, a, b, c, s, batch_count) |
Detailed Description
BLAS Level 1 API.
rotg_batched creates the Givens rotation matrix for the batched vectors (a_i b_i), for i = 1, ..., batch_count. a, b, c, and s may be stored in either host or device memory, location is specified by calling rocblas_set_pointer_mode. If the pointer mode is set to rocblas_pointer_mode_host, this function blocks the CPU until the GPU has finished and the results are available in host memory. If the pointer mode is set to rocblas_pointer_mode_device, this function returns immediately and synchronization is required to read the results.
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in,out] a device array of device pointers storing each single input vector element a_i, overwritten with r_i. [in,out] b device array of device pointers storing each single input vector element b_i, overwritten with z_i. [in,out] c device array of device pointers storing each cosine element of Givens rotation for the batch. [in,out] s device array of device pointers storing each sine element of Givens rotation for the batch. [in] batch_count [rocblas_int] number of batches (length of arrays a, b, c, and s).
