Hi,

I'm learning to program with functions, and I'm finding it difficult to debug them. I was wondering if there was a way to access variables that are used only within functions after stopping execution or after an error. Thanks for any help!

From the command line try: dbstop if error

Yes of course. Just set the breakpoint and hover your cursor over the
variable. Type control-D if you want to bring it up in the variable
editor panel, which will let you see larger and more complicated
variables than hovering can show. If you're stopped in your function,
then you will be able to see the variables that are in scope there in
your function.

Yes; use the debugging capabilities built into MATLAB and the MATLAB Editor:

http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_env/f2-4931.html

The short, short version: click on the little lines next to the line
numbers when the file is open in the Editor to set a breakpoint; when you
run the code, MATLAB will enter debug mode when it reaches the breakpoint.
Use DBSTEP or DBCONT when you want to step through the code or continue
execution.
