get the list of simulink constant block in matlab

You can get the list of all the Simulink constant blocks in a Simulink model in MATLAB using the following steps:

1. Open the Simulink model in MATLAB.
2. Use the find_system command to get the handles of all the blocks in the model.
3. Use a loop to check the block type of each block.
4. If the block type is a constant block, then add it to the list of constant blocks.

Here's the code to implement the above steps:

main.m
% Get the handles of all the blocks in the model
blocks = find_system(gcb, 'Type', 'Block');

% Initialize the list of constant blocks
const_blocks = {};

% Loop through each block in the model
for i = 1:length(blocks)
    % Get the block type
    block_type = get_param(blocks{i}, 'BlockType');
    
    % Check if the block type is a constant block
    if strcmp(block_type, 'Constant')
        % Add the block to the list of constant blocks
        const_blocks{end+1} = blocks{i};
    end
end

% Print the list of constant blocks
disp(const_blocks);

Note that gcb in the above code represents the current Simulink model that is open in MATLAB. Also, the strcmp function is used to compare the block type with the string 'Constant'.
