Stop and Continue Iterations

I am running a loop as follows:
tol = 1e-6;
while err < tol
% code
disp(tol)
end
During runtime, I decide to stop and check something, and continue the running the program again. I can do this using Ctrl+C, but the program terminates inside the loop, which is undesirable. Is it possible to stop the iterations and continue again in some other way.

As of version MATLAB 2016a you can pause the execution of a running file. prior to this you would need to place a breakpoint if you want it to stop inside the loop. If you know the condition on which you want it to stop you can place a conditional breakpoint.

Click the pause button on the tool ribbon, next to the Run button. It looks like the pause button on media players, like two vertical bars.

Kiran, one hack if you don't want to use the pause button and you're in a loop is to just put an if in the loop to stop at some particular iteration you know in advance
if k == 42
; % Set a breakpoint on this line
end
but the preferred way is to just put a conditional breakpoint on the line. Click the down arrow on the Breakpoints button and select Set Condition. Then type k == 42 into the condition edit field.
With the pause button, you don't know what iteration you will be in when you stop, but with the conditional breakpoint, you will.

Instead of leaving that middle line empty except for a semicolon, call keyboard on it.
