Search is getting failed for a library usage in Simulink model

I wanted to search number of instances of a library being used in the entire simulink model and also wanted to know all the path where the library is being is used.

But it is not working and says "Search Failed"

I have already increased "Java Heap Memory" to MAX in preferences.

Also deleted all temp files from temp folder and restarted PC and Matlab but still problem exists.

Hi @Balaji V,

As a workaround, you can try programmatically searching for the number of instances of a library by following the example mentioned below:

% Loads the Simulink model named 'example.slx'
expLib = load_system('example.slx');

% Find all blocks within the loaded system, including those under masks
expLibBlocks = find_system(expLib, 'LookUnderMasks', 'all', 'Type', 'Block');

% Retrieve the block types of all found blocks and store them in an array
blockTypeArray = get(expLibBlocks, 'BlockType');

To count the number of occurances, you can use the following function. Please note that if you're using a custom library block, this function will not be able to count the occurrences of its subsystem.

function count = countStringOccurrences(cellArray, searchString)
    % countStringOccurrences counts the occurrences of a string in a cell array.
    
    % Initialize the count to zero
    count = 0;
    
    % Loop through each element in the cell array
    for i = 1:length(cellArray)
        % Check if the current element is a string and matches the search string
        if ischar(cellArray{i}) && strcmp(cellArray{i}, searchString)
            % Increment the count if a match is found
            count = count + 1;
        end
    end
end

Here's an example of the "countStringOccurrences" function being used.

numOfOccurences = countStringOccurrences(blockTypeArray, 'Outport')

To programmatically find the path of a library block in a model, you can use the following code snippet:

pathOfTheBlock = get(find_system(ex, 'Name', 'Outport')).Path

I hope this helped, thanks!

Thank you. Will check it.
