how to use load.filename command in matlab

The load command in MATLAB is used to load variables from a file. The load filename command is used to load variables from the file with the given filename. Here's an example of how to use it:

main.m
% Load variables from the file data.mat
load data.mat

% Use the variables in your code
disp(['X = ', num2str(X)])
disp(['Y = ', num2str(Y)])
142 chars
7 lines

In this example, MATLAB will look for a file called data.mat in the current directory and load any variables that it finds in the file. You can then use these variables in your code as you would any other variables.

Note that the load command is not restricted to files with a .mat extension. It can be used to load variables from any file that contains properly formatted MATLAB data.
