make a graph in matlab

To make a graph in Matlab, we typically use the plot function. This function takes a set of x and y coordinates and generates a line plot. Here's an example:

main.m
% Create some data
x = 1:10;
y = x.^2;

% Plot the data
plot(x,y);

% Add labels to the x and y axes
xlabel('X values');
ylabel('Y values');

11 lines

This code will generate a line plot with the x values on the x-axis and y values on the y-axis. The xlabel and ylabel functions are used to add labels to the x and y axes, respectively.

There are many options available for customizing the appearance of the plot - such as changing the line color, thickness, and style - but the basic plot function and axis labeling are the most important elements to start with.
