Toolbox containing general method for the forward models. Most of these are for diffusion based calculations.

Evaluate the Hankel transform using a digital fitler method for the quadrature points. Necessary to have a continuous function for transformation.

Class used to compute the discrete Fourier transform of a reflectance curve.

Transforms linearly discrete data via a middle Riemann sum. This method is not mathematically sound, but is a low order approximation.
