Plotting 2D and 3D Curves in MATLAB

By RF Wireless Expert Team

This page covers plotting functions for 2D and 3D curves in MATLAB, focusing on the plot and plot3 functions.

plot and plot3 MATLAB Code

Here’s an example demonstrating the plot and plot3 functions:

clc;
clear all;
close all;

x = [1 2 3 4 5 6 7 8 9 10];
y = [0.1 0.2 0.3 0.4 0.5 0.35 0.25 0.15 0.05 0.02];
z = [10 20 30 40 50 60 70 80 90 100];

figure;
plot(x, y);

figure;
plot3(x, y, z);

Another example using plot3:

clc;
clear all;
close all;

t = linspace(0, 1, 1000);
x = t;
y = t.^2;
z = t.^3;

plot3(x, y, z);

Output image:

stem3 Function

Another useful MATLAB function for plotting in 3D is stem3(x,y,z). This creates a 3D stem plot.
