When I insert breakpoints inside a parfor loop it is never stopped. In this case how can I debug inside a parfor loop?

Please show your code, have you use break statement within parfor loop with a condition?

You can debug code called from the body of a parfor loop if no parallel pool is open, but unfortunately you cannot debug the body of a parfor loop itself. You can force the parfor loop to run in the desktop MATLAB by appending the optional "number of workers" argument, like so:
parfor (idx = 1:10, 0)
out(idx) = myFcn(idx);
end
With that code, you can set breakpoints inside myFcn.

Change the parfor to for debug it and then change for to parfor

For those who are seeking for the solution, there is another possible option by using parfor and try-catch:
parfor k = 1: len
try
% your code
catch ME
% record the iteration index,k
end
end
% Then youy know which iteration caused a bug alert
