how to calculate the probability of a laplace distribution in matlab

To calculate the probability of a Laplace distribution in MATLAB, you can use the laplacepdf function from the Statistics and Machine Learning Toolbox. The laplacepdf function computes the Laplace probability density function at each value in x, using the mean mu and scale b.

Here's an example usage:

main.m
% Define the parameters of the Laplace distribution
mu = 0;
b = 1;

% Define the range of x values to calculate the probability for
x = -5:0.1:5;

% Calculate the probability density function using laplacepdf
pdf = laplacepdf(x, mu, b);

% Plot the probability density function
plot(x, pdf);

In this example, we define the mean mu and scale b of the Laplace distribution, and then calculate the probability density function pdf using the laplacepdf function for a range of x values. Finally, we plot the pdf using the plot function.
