Detailed Description

template<typename ReturnT>
class lsst::afw::math::LanczosFunction2< ReturnT >

2-dimensional separable Lanczos function

f(x, y) = sinc(pi x') sinc(pi x' / n) sinc(pi y') sinc(pi y' / n) where x' = x - xOffset and y' = y - yOffset and coefficients c0 = xOffset, c1 = yOffset

Warning
the Lanczos function is sometimes forced to 0 if |x'| > n or |y'| > n but this implementation does not perform that truncation so as to improve Lanczos kernels.

This function exists instead of a copy constructor so one can obtain a copy of an actual function instead of a useless copy of the base class.

Every non-virtual function must override this method.

Returns
a pointer to a deep copy of the function
