scripts default iconInteger order Hankel transform (Scripts) Publisher's description

This routine implements Hankel transforms of integer order based on a Fourier-Bessel series expansion

This routine implements Hankel transforms of integer order based on a Fourier-Bessel series expansion. The algorithm is based on a recently published research work:

M. Guizar-Sicairos and J. C. Gutierrez-Vega, Computation of quasi-discrete Hankel transforms of integer order for propagating optical wave fields,
J. Opt. Soc. Am. A 21, 53-58 (2004).

The numerical method features great accuracy and is energy preserving by construction, it is especially suitable for iterative transformation

With the c.mat array, that contains Bessel functions zeros, Hankel transforms of order 0-4 may be computed, with up to 3000 sampling points. A trasformation, and inverse transformation example is given.

This routine was tested under MATLAB 6.5 R13

System Requirements:

MATLAB 6.5 (R13)
Program Release Status: New Release
Program Install Support: Install and Uninstall
