| integer(kind(hipblas_status_success)) function | hipblaszrotgbatched_ (handle, a, b, c, s, batchCount) |
Detailed Description
BLAS Level 1 API.
rotgBatched creates the Givens rotation matrix for the batched vectors (a_i b_i), for i = 1, ..., batchCount. a, b, c, and s may be stored in either host or device memory, location is specified by calling hipblasSetPointerMode. If the pointer mode is set to HIPBLAS_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 HIPBLAS_POINTER_MODE_DEVICE, this function returns immediately and synchronization is required to read the results.
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas 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] batchCount [int] number of batches (length of arrays a, b, c, and s).
