Performs rotation of points in the plane.
void rot(queue &exec_queue, std::int64_t n, buffer<T,1> &x, std::int64_t incx, buffer<T,1> &y, std::int64_t incy, T_scalar c, T_scalar s);
rot supports the following precisions and devices.
T | T_scalar | Devices Supported |
---|---|---|
float | float | Host, CPU, and GPU |
double | double | Host, CPU, and GPU |
std::complex<float> | float | Host, CPU, and GPU |
std::complex<double> | double | Host, CPU, and GPU |
Given two vectors x and y of n elements, the rot routines compute four scalar-vector products and update the input vectors with the sum of two of these scalar-vector products as follow:

The queue where the routine should be executed.
Number of elements in vector x.
Buffer holding input vector x. The buffer must be of size at least (1 + (n - 1)*abs(incx)). See Matrix and Vector Storage for more details.
Stride of vector x.
Buffer holding input vector y. The buffer must be of size at least (1 + (n - 1)*abs(incy)). See Matrix and Vector Storage for more details.
Stride of vector y.
