how to reverse a plot in matlab

To reverse the direction of an axis in MATLAB, you can use the set function to change the XDir or YDir property of the current axis. Here's an example of how to reverse the x-axis direction of a plot:

main.m
% Generate some sample data
x = linspace(0, 2*pi, 100);
y = sin(x);

% Plot the data
plot(x, y);

% Reverse the x-axis direction
set(gca, 'XDir', 'reverse');

In this example, the plot function creates a sinusoidal curve, and the set function with 'XDir', 'reverse' argument reverses the direction of the x-axis.
