how to calculate the probability of a rayleigh distribution in matlab

To calculate the probability density function (pdf) of a Rayleigh distribution in MATLAB, you can use the raylpdf function, which takes two input arguments:

main.m
x = 0:0.1:10;
b = 2; % scale parameter
pdf = raylpdf(x, b);

4 lines

In this example, x is a vector of values at which to evaluate the pdf, and b is the scale parameter of the distribution. The output pdf is a vector of the same size as x containing the pdf values at each point.

To visualize the pdf, you can use the plot function:

main.m
plot(x, pdf)
xlabel('x')
ylabel('pdf')
title('Rayleigh distribution')

5 lines

This will generate a plot of the pdf values versus x, with an x-axis label of "x", a y-axis label of "pdf", and a title of "Rayleigh distribution".
