progress_bar is a lightweight method of giving a progress and time indication when running an calculation intensive for-loop.
Al that is required is to include the function within the for loop such as:
| for idx=min:max
| progress_bar(idx, min, max);
Additional options include a custom message, or a GUI progress bar using waitbar.
The time added to your calculation depends on the intensity of the calculation done in each iteration and the number of iteration and is typically less than 1% for the default text version.
