if you are frequently using Matlab and you want the image sync functionality of nomacs, you can download this Matlab script and add it to your Matlab folder. Matlab images can then be displayed by typing:

    This has been done by nomacs by allowing people to view (and edit) their images with its “appergonomic” ease.

    Piece by piece, plugin by plug-in features will be added by those that were attracted to nomacs by its ease of use therefore making sure each plugin is finely tuned to maintain nomacs most important feature, to allow one to use a compu’r without
