Detailed Description
!
BLAS Level 1 API
\details
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 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.
@param[in]
handle [rocblas_handle]
handle to the rocblas library context queue.
@param[inout]
a device pointer or host pointer to input vector element, overwritten with r.
@param[inout]
b device pointer or host pointer to input vector element, overwritten with z.
@param[inout]
c device pointer or host pointer to cosine element of Givens rotation.
@param[inout]
s device pointer or host pointer sine element of Givens rotation.
