### Lanczos4

They are from open source Python projects. If the calculated destination value lies outside of the main contributors' value range, make sure that the destination value is modified to fit into range. sinc (πx) sinc (πx/4) for |x| < 4 The Lanczos methods belong to the general class of windowed sinc (x) interpolation methods. The Lanczos algorithm is a direct algorithm devised by Cornelius Lanczos that is an adaptation of power methods to find the "most useful" (tending towards extreme highest/lowest) eigenvalues and eigenvectors of an × Hermitian matrix, where is often but not necessarily much smaller than.
