Matlab is a powerful programming language that allows you to create and manipulate data. One of the most common tasks that you will perform in Matlab is manipulating variables. Variables are important because they allow you to control the behavior of your code. When you delete a variable, Matlab deletes the data that it contains for that variable. This can cause problems if your code depends on the value of a variable that has been deleted. To delete a variable in Matlab, use the following command: matlab -d vars
