# Whittaker–Shannon interpolation in Haskell

Haskell implementation for converting a list of numbers to a continuous time function using Whittaker–Shannon interpolation. The formula for the interpolation is given by

![formula](https://wikimedia.org/api/rest_v1/media/math/render/svg/a6fb0ab1bd8507bc90a23bf0435888d2105c7449)

Check out the [wikipedia](https://en.wikipedia.org/wiki/Whittaker%E2%80%93Shannon_interpolation_formula) article for more information. An example of the resampling is shown in the figure below.
