How to find Matlab Function blocks in a model?

I would like to use find_system to find all MATLAB Function blocks (from the User-Defined Functions library) in a model. The problem is that all MATLAB Function blocks are of BlockType SubSystem. What parameters can I use to only find the MATLAB Function blocks?

isMLfunction = strcmp(get_param(gcb, 'SFBlockType'), 'MATLAB Function');

Hi Hadi Zyien

Yes, We have to use find_system to find matlab function block. After that, we need to use get_param command for finding matlab function block. Matlab Function block will have three to four parametes, as like

get_blocks ={' Demux ';' Ground ';' SFunction ';' Terminator '};

Use below code.

clc
clear
find_mat_fn = find_system(gcs,'BlockType','SubSystem'); % finding Subsytem
mat_fn = {' Demux ';'Ground';' SFunction ';' Terminator '}; % default parameter for Matlab Function Block
mat_blk_name = 1;
for i = 1 : length(find_mat_fn)
    get_blocks = get_param(find_mat_fn{i}, 'Blocks');   % Blocks will returns what are the blocks used in subsystem
    check_block =  find(ismember(get_blocks,mat_fn) == 1); % comparing with default parameter
    if check_block
        matlab_fcn_blck{mat_blk_name} = find_mat_fn{i};
        mat_blk_name = mat_blk_name + 1;
    end
end
disp(matlab_fcn_blck)

Hi Murugan,

Unfortunately this approach also returns Stateflow charts.

Use the following code lines to find MATLAB function blocks:

rt = sfroot;
m = rt.find('-isa','Stateflow.EMChart')

It uses the powerfull yet under-recognized Stateflow API https://fr.mathworks.com/help/stateflow/ref/sfroot.html

Despite its name, I believe it is available with Simulink alone.
