Detailed Description
BLAS Level 1 API.
The rotm functions apply the modified Givens rotation matrix defined by param to vectors x and y.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] n - [rocblas_int] number of elements in the x and y vectors. [in,out] x - device pointer storing vector x. [in] incx - [rocblas_int] specifies the increment between elements of x. [in,out] y - device pointer storing vector y. [in] incy - [rocblas_int] specifies the increment between elements of y. [in] 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.
