# OEGeom2DRotate¶

template<class T, class U>
void OEGeom2DRotate(T *xyz, const U *m, unsigned int ncoord)


Rotates the two dimensional coordinates by the $$2 \times 2$$ rotation matrix passed as the argument m. For ncoord sets of coordinates the input array xyz is expected to have a length of $$2*ncoord$$.

xyz

Array of coordinates to rotate

m

Rotation matrix

ncoord

Number of coordinate sets
