Can you programmatically create a custom filter for Simulink model diffs?

We have some blocks in our models that we basically always want to ignore when doing a model diff, and I have made a filter for that. But as of right now, the only way to get that to other people working on the models is to export the filters, and then they manually import the filters. It would be ideal if the filters could be setup progromatically, either through the project file, or some other method to edit the definition, that way everyone would always have the same base filters.
Anyone know where the filters are defined for the user? Can I get into the xml file somewhere?

Hey Scott,
I understand that you are facing a challenge with distributing and synchronizing model comparison filters. You seek a method to programmatically establish these filters, ensuring consistent settings for model comparisons thus streamlining the proces.
One possible way can be creating the necessary comparison filter manually, locating the XML file where this filter is defined, and then writing a MATLAB script to distribute and apply this filter across different setups. This script can copy the predefined filter XML file to the appropriate directory on each user's machine. Here's how you could implement such a script:
function setupComparisonFilter(filterFileName, destinationFolder)
% Copy the filter file to the destination directory
% filterFileName is the path to the XML filter file you want to distribute
% destinationFolder is the target directory on the user's machine, typically within MATLAB's prefdir directory
% Example destinationFolder: fullfile(prefdir, 'ModelComparison', 'filters')
if ~exist(destinationFolder, 'dir')
mkdir(destinationFolder);
end
[filterFileFolder, filterBaseName, ext] = fileparts(filterFileName);
destinationFile = fullfile(destinationFolder, [filterBaseName, ext]);
% Copy the file
copyfile(filterFileName, destinationFile);
% Inform the user
fprintf('Filter file copied to: %s\n', destinationFile);
% Note: Additional steps may be required to set this filter as the default.
end
However this script assumes you have already created a filter and know the path to its XML file. It copies this filter to a specified directory, which should align with where MATLAB looks for these filters on startup.

Hope this helps !
