Getting Started with MATLAB

This is a short introductory tutorial designed to provide a brief overview of fundamental MATLAB concepts, including basic arithmetic operations, graph plotting, scripts, and user-defined functions.

The tutorial intentionally incorporates common mistakes to expose students to typical error messages, helping them develop the ability to interpret and debug MATLAB code effectively.

Broken on Purpose: Can You Rescue This MATLAB Plot?

The following code is intended to generate a plot of an exponentially decaying sinusoid, similar to the one shown in Figure 1. However, the script contains three deliberate errors and will not execute correctly as written.

t = linspace(0, 10, 1000);

y = exp(-0.3*t)*sin(2*pi*t);

plot(y, T)

Your task is to identify and correct the errors so that the code runs successfully and produces the graph shown in Figure 1.
