Performs rotation of points in the plane.
event rot(queue &exec_queue, std::int64_t n, T *x, std::int64_t incx, T *y, std::int64_t incy, T_scalar c, T_scalar s, const vector_class<event> &dependencies = {});
The USM version of 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:
EQUATION HERE
The queue where the routine should be executed.
Number of elements in vector x.
Pointer to input vector x. The array holding input vector x must be of size at least (1 + (n - 1)*abs(incx)). See Matrix and Vector Storage for more details.
Stride of vector x.
Pointer to input vector y. The array holding input vector y must be of size at least (1 + (n - 1)*abs(incy)). See Matrix and Vector Storage for more details.
Stride of vector y.
Scaling factor.
Scaling factor.
List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.
Pointer to the updated matrix x.
Pointer to the updated matrix y.
Output event to wait on to ensure computation is complete.
