How to compare between simulink setting file

visdiff command is not what i wanted..

What do you mean by "visdiff is not what I wanted"?

What is your pain point on visdiff? Or what do you actually want?

Hello Dayoung,

Here is a workaround to compare Simulink setting files without using the ‘visdiff’ function. It is assumed that your Simulink files produce a ‘Simulink.ConfigSet’ object, which contains configurations for the Simulink models. Below is an example to demonstrate how two such ‘Simulink.ConfigSet’ objects can be compared:

• Convert the ‘Simulink.ConfigSet’ object into a structure.

structure1 = getConfigSetAsStruct(configSet1);
structure2 = getConfigSetAsStruct(configSet2);

function settingsStruct = getConfigSetAsStruct(configSet)
    % Get the names of configuration
    paramNames = get_param(configSet, 'ObjectParameters');
    
    % Create a structure
    settingsStruct = struct();
    
    % Loop through each configuration and add it to the structure
    for paramName = fieldnames(paramNames)'
        paramNameStr = paramName{1};
        paramValue = get_param(configSet, paramNameStr);
        settingsStruct.(paramNameStr) = paramValue;
    end
end

• Create a structure named ‘differences’ to store any differences found between the settings files.

differences = struct(); 

• Check for configurations that are only present in either of the setting files.

% Get the names of configuration from both the structures
fields1 = fieldnames(structure1);
fields2 = fieldnames(structure2);

% Check for fields that are only in first structure
onlyIn1 = setdiff(fields1, fields2);
if ~isempty(onlyIn1)
    differences.onlyIn1 = onlyIn1;
end

% Check for fields that are only in second structure
onlyIn2 = setdiff(fields2, fields1);
if ~isempty(onlyIn2)
    differences.onlyIn2 = onlyIn2;
end

• Check for configurations that are present in both files but have different values.

% Check for fields that are common, but differ in values
commonFields = intersect(fields1, fields2);
for i = 1:length(commonFields)
    field = commonFields{i};
    if ~isequal(structure1.(field), structure2.(field))
        differences.(field) = struct('settings1', structure1.(field), 'settings2', structure2.(field));
    end
end

• In the end, the ‘differences’ structure will store the discrepancies found in the two Simulink setting files.
