how to add multiple functions in a single Simulink MATLAB function file?

here i have generated seperate .m function files, all function files called many times in script code and it works fine..

Now,

I need to make simulink block using MATLAB Function block, which upon giving inputs should generate output by solving multiple functions in one block (like script having many function and run smoothly to give solution)..

How to make this in simulink,

Help is appreciated.

Hi,

You can make use of the MATLAB function block in Simulink. Refer to the below steps for a better understanding:

1. Create a blank model in Simulink.
2. Navigate to the Library Browser
3. Go to User-Defined Functions under Simulink.
4. Select MATLAB function block.
5. Double-click the MATLAB function block to open the editor.
6. You can now implement your functions or call the separate function files from this block.

You can make changes in the editor in the following manner:

function y = fcn(x)
    % Call external functions
    a = function1(x);
    b = function2(a);
    y = function3(b);
    % Add more function calls as needed
end

For more information on MATLAB function block refer to the below documentations:
