How to disable the progress bar when using the nlfilter function in Matlab?

Question

Each time I call the nlfilter function a progress bar window appears. How could I disable that window?. Is there an option like -q?

The waitbar within MATLAB definitely reduces the performance of your code as well as gets really obnoxious when running long-running tasks on some operating systems as it can steal the focus of your keyboard/mouse randomly.

I personally create my own waitbar function and place it on the MATLAB path so that it is evaluated rather than the built-in.

I have a more complicated text-based progress bar, but the following function will simply print the messages to the command line. You could even remove the first block and have the contents simply be varargout = {[]}; and you will have no output.

function varargout = waitbar(varargin)
    if nargin >= 2 && ischar(varargin{2})
        disp(varargin{2})
    elseif nargin >= 3 && ischar(varargin{3})
        disp(varargin{3})
    end
    varargout = {[]};
end

Be sure to save this in waitbar.m somewhere high on your MATLAB path.

NOTE: This will silence all waitbars so if you want to restore the typical waitbar behavior, you will want to remove/rename this file.
