| integer(kind(rocblas_status_success)) function | rocblas_zrotg_strided_batched_ (handle, a, stride_a, b, stride_b, c, stride_c, s, stride_s, batch_count) |
Detailed Description
BLAS Level 1 API.
rotg_strided_batched creates the Givens rotation matrix for the strided 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 strided_batched pointer or host strided_batched pointer to first single input vector element a_1, overwritten with r. [in] stride_a [rocblas_stride] distance between elements of a in batch (distance between a_i and a_(i + 1)) [in,out] b device strided_batched pointer or host strided_batched pointer to first single input vector element b_1, overwritten with z. [in] stride_b [rocblas_stride] distance between elements of b in batch (distance between b_i and b_(i + 1)) [in,out] c device strided_batched pointer or host strided_batched pointer to first cosine element of Givens rotations c_1. [in] stride_c [rocblas_stride] distance between elements of c in batch (distance between c_i and c_(i + 1)) [in,out] s device strided_batched pointer or host strided_batched pointer to sine element of Givens rotations s_1. [in] stride_s [rocblas_stride] distance between elements of s in batch (distance between s_i and s_(i + 1)) [in] batch_count [rocblas_int] number of batches (length of arrays a, b, c, and s).
