PDF and CDF of rician distribution simulation source

Hello everyone, I'm entirely new to matlab and I have an assignment that must be submitted within 2 days time. I found the simulated image but not the code https://en.wikipedia.org/wiki/File:Rice_distributiona_PDF.png for pdf and https://en.wikipedia.org/wiki/File:Rice_distributiona_CDF.png for cdf. I need your help with the source code guys

[Torsten]

Use

random('Rician',s,sigma)

to generate random numbers from a Rice distribution.

I appreciate the help guys. All I need is a source code to simulate rice/rician PDF and CDF in matlab. I study after work guys, I don't have time to learn new programming within a week which means less than 1 day of spare time if I put it in hours.

What is 's' over here. please explain me this in term of shape and scale parameter. Your answer is highly appreciable.

[Jeff Miller]

s is shape, sigma is scale: https://au.mathworks.com/help/stats/rician-distribution.html

Answer 1

[Jeff Miller]

Why can't you use this:

pd = makedist('Rician')

Jeff Miller, thanks for the reply but how can I plot this? I need an output like this for rician PDF and CDF

Answer 2

[Jeff Miller]

OK, here's a more complete answer:

pd = makedist('Rician','s',0,'sigma',2);  % Change to your required parameters
N = 1000;  % size of random sample
x = pd.random(N);
histogram(x,'Normalization','pdf');
xpts = min(x):0.001:max(x);
xpdf = pd.pdf(xpts);
hold on;
plot(xpts,xpdf,'r- ','Linewidth',5);
