MATLAB subplot

MATLAB subplot

In MATLAB, a subplot is a way to display multiple plots on a single figure window. The syntax for creating a subplot in MATLAB is:

subplot(m, n, p)

Where m and n are the number of rows and columns of subplots, respectively, and p is the specific subplot number. For example, the command subplot(2, 2, 1) will create a figure window with two rows and two columns of subplots, and it will create the first subplot (upper left).

To create multiple subplots in a single figure window, you can use the subplot command multiple times. For example, to create four subplots arranged in a 2x2 grid, you could use the following commands:

subplot(2, 2, 1)
subplot(2, 2, 2)
subplot(2, 2, 3)
subplot(2, 2, 4)

Once you have created the subplots, you can use the usual plotting commands (such as plot, scatter, etc.) to plot data in each subplot. For example, to plot a sine wave in the first subplot and a cosine wave in the second subplot, you could use the following commands:

x = 0:0.1:10;
subplot(2, 2, 1)
plot(x, sin(x))
subplot(2, 2, 2)
plot(x, cos(x))

You can also customize the appearance of your subplots, such as the title, axis labels, and legend. For example, to add a title and axis labels to the first subplot, you could use the following commands:

subplot(2, 2, 1)
plot(x, sin(x))
title('Sine Wave')
xlabel('x')
ylabel('sin(x)')
