MATLAB: Function Call Output Simulink Modelisation

function call outputmatlab functions blockssimulink

Hi,
I've made a Simulink model including 2 Matlab Functions blocks as an example for learning how to use Function Call Output for an embedded MATLAB Function block.
I've added the Function Call Output (Edit data/Add/Function Call Output on Matlab). The thing is, I don't know what to do next, how do you model that on Simulink?
Thanks

You can't call one MATLAB function block from another MATLAB Function block. See here. Rather than having the code for fcn1() in a MATLAB function block, do the following:
1. place the code into a file called fcn1.m. Place this file in the same directory as your simulink model or in a directory that is on the MATLAB path.
2. Delete MATLAB Function Fcn1 block
3. Modify MATLAB Function Fcn block to remove the function call fcn1 from the data dictionary.
