MATLAB: Breakpoints in code. Something equivalent to the Stop command in interpreted Basic.

breakpointMATLABstop

I'm wanting to put permanent breakpoints in code. Something equivalent to the Stop command in interpreted Basic. As with the Editor's breakpoints, I want the cursor to be at the interruption point. And I want to continue with F5. Any ideas?

MATLAB: How to “watch” variables using the MATLAB Debugger

In order to "watch" a variable, you can set a conditional breakpoint to stop when a certain condition is met. You can select a conditional break point interactively from the editor tab in MATLAB R2012b or newer, or through the command line.

For example, to stop in debug mode when ii is equal to 25, in the file "watched.m", which consists of the following:

for ii = 1:100
      disp(ii)
end

You could run:

dbstop in watched at 2 if (ii == 25)
