Either use echo or the debugger. Some disp statements at the relevant lines (the ones, which consume the most time) would be helpful also.

Another option, other than echo, is to hit the pause button, though that will just stop on the currently executing line, whereas echo will stream all the lines of code to the command window as they are executing.

Note: the pause button is fairly new, no earlier than R2016a (might have been R2016b)

hi, with profiler and profile_history you can get the executed lines in each function and functions executed.

[Walter Roberson]

True, but that does not tell you which line is currently executing.
