Detailed Description
BLAS Level 1 API.
The rotmg functions create the modified Givens rotation matrix for the vector (d1 * x1, d2 * y1 ). Parameters can be stored in either host or device memory. The location is specified by calling rocblas_set_pointer_mode:
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in,out] d1 - device pointer or host pointer to input scalar that is overwritten. [in,out] d2 - device pointer or host pointer to input scalar that is overwritten. [in,out] x1 - device pointer or host pointer to input scalar that is overwritten. [in] y1 - device pointer or host pointer to input scalar. [out] param - device vector or host vector of five elements defining the rotation. param[0] = flag param[1] = H11 param[2] = H21 param[3] = H12 param[4] = H22
The flag parameter defines the form of H:flag = -1 => H = ( H11 H12 H21 H22 ) flag = 0 => H = ( 1.0 H12 H21 1.0 ) flag = 1 => H = ( H11 1.0 -1.0 H22 ) flag = -2 => H = ( 1.0 0.0 0.0 1.0 )
param can be stored in either host or device memory. The location is specified by calling rocblas_set_pointer_mode.
