Public Member Functions
integer(kind(hipblas_status_success)) function	hipblassrotg_ (handle, a, b, c, s)

Detailed Description

BLAS Level 1 API.

The rotg functions create the Givens rotation matrix for the vector (a b). Scalars c and s and arrays a and b can be stored in either host or device memory. The 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.

• Supported precisions in rocBLAS : s, d, c, and z.
• Supported precisions in cuBLAS : s, d, c, and z.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in,out]	a	- device pointer or host pointer to the input vector element, overwritten with r.
[in,out]	b	- device pointer or host pointer to the input vector element, overwritten with z.
[in,out]	c	- device pointer or host pointer to the cosine element of the Givens rotation.
[in,out]	s	- device pointer or host pointer to the sine element of the Givens rotation.
