Detailed Description
!
BLAS Level 1 API
\details
rotm applies the modified Givens rotation matrix defined by param to vectors x and y.
@param[in]
handle [rocblas_handle]
handle to the rocblas library context queue.
@param[in]
n [rocblas_int]
number of elements in the x and y vectors.
@param[inout]
x device pointer storing vector x.
@param[in]
incx [rocblas_int]
specifies the increment between elements of x.
@param[inout]
y device pointer storing vector y.
@param[in]
incy [rocblas_int]
specifies the increment between elements of y.
@param[in]
param device vector or host vector of 5 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 may be stored in either host or device memory, location is specified by calling rocblas_set_pointer_mode.
