File Information

Low-pass filtering is easy and always works fine (not included here). High-pass filtering needs conversion of numbers from integer to float before processing and then conversion back to integer -- to keep numbers within their limits.

in order to avoid this you should add this line of code into your file,
imtool close all; % Close all imtool figures.
