Using Warnings to Help Debug
You can detect erroneous or unexpectedbehaviorinyourprogramsby
inserting warning messages that MATLAB will display under the conditions
you specify. See the section on “Warning Control” on page 8-16 in the
documentation to find out how to selectively enable warnings.
For more information: See the warning function reference page.

Then, run your program and the evaluation of that statement is displayed

Debugging Scripts
Scripts store their variables in a workspace that is shared with the caller of
the script. So, when you debug a script from the command line, the script uses
variables from the base workspace. To avoid errors caused by workspace
sharing, type clear all before starting to debug your script to clear the
base workspace.
