debug

Description

debug lists M-file debugging functions.

Use debugging functions (listed in the See Also section) to help you identify problems in your M-files. Set breakpoints using dbstop. When MATLAB^® software encounters a breakpoint during execution, it enters debug mode, the Editor becomes active, and the prompt in the Command Window changes to a K>>. Any MATLAB command is allowed at the prompt. To resume execution, use dbcont or dbstep. To exit from debug mode, use dbquit.

To open the M-File in the Editor when execution reaches a breakpoint, select Debug > Open M-Files When Debugging.
