| integer(kind(hipblas_status_success)) function | hipblaszrotg_ (handle, a, b, c, s) |
Detailed Description
BLAS Level 1 API.
rotg creates the Givens rotation matrix for the vector (a b). Scalars c and s and arrays a and b 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 pointer or host pointer to input vector element, overwritten with r. [in,out] b device pointer or host pointer to input vector element, overwritten with z. [in,out] c device pointer or host pointer to cosine element of Givens rotation. [in,out] s device pointer or host pointer sine element of Givens rotation.
