create a graphic in matlab

To create a graphic in Matlab, you need to use the plot and figure functions. The plot function is used to plot data in a 2D plot, while the figure function creates a new figure window. Here's an example code to create a simple line plot:

main.m
% Define data
x = [0:0.1:5];
y = sin(x);

% Create a new figure window
figure()

% Plot data
plot(x, y)

% Add title and axis labels
title('Sine Wave')
xlabel('x')
ylabel('y')

15 lines

In this example code, we define some data (x and y), create a new figure window using the figure function, and plot the data using the plot function. Finally, we add a title and axis labels to the plot.

There are many other options and features that you can use to customize your Matlab graphics, such as changing line colors and styles, adding legends, and creating multiple plots in a single figure. The Matlab documentation provides a comprehensive guide to these features.
