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!
