Functions for Rice/Rician PDF: stats, samples, and distribution fitting.

File Information

Functions for Rice/Rician PDF: summary statistics (mean and variance), generating random samples, and simple moment-matching to fit the distribution to data.

Similar to e.g. normpdf, normstat, normrnd and normfit from the MATLAB statistics toolbox, but for the Rice distribution, which is useful in Communications and Magnetic Resonance Imaging.

ricepdf - Rice/Rician probability density function (pdf).

ricestat - Mean and variance of Rice/Rician probability distribution.

ricernd - Random samples from the Rice/Rician probability distribution.

ricefit - Estimate parameters for Rice/Rician distribution from data.

ricedemo - Rice/Rician Distribution Demo.

MATLAB release MATLAB 7.4 (R2007a)

Very good package and great for my problem. Thanks.
I have uploaded a faster version that operates on multiple set at once. I called it "ricefit_fast", same syntax.

Does not call external functions (which is very good). Easy to follow and well commented.

Nice and Thanks!

Added ricefit (which is rather naive, but possibly useful)

Corrected error in zip-file.
