Hello, I have problem with my s-function
Error in 'Celanovic_3niv2/Nearest three vectors/S-Function' while executing MATLAB S-function 'Celanovic', flag = 3 (output), at time 0.0.
And this is my s-function:
function [sys,x0,str,ts] = Celanovic(t,x,u,flag)

Could you please help me with my problem.

You didn't specify the error message, but I would recommend setting breakpoints in your code to understand the issue better.

I had a similar error:
An error occurred while running the simulation and the simulation was terminated
Error in 'circ1_2015/Ball Mill/Product Calculation/Product S-Func (tph by size)' while executing MATLAB S-function 'BM_Prod_2015', flag = 3 (output), at time 0.0.
Data points in complex number format are not supported. Use REAL and IMAG to extract the real and imaginary components. Component: Simulink | Category: Block error
--------------
I'm still trouble shooting it. The S-function code and model file were originally Matlab 11. Upgrade was completed successfully with all checks green and good to go. It still could be an upgrade issue...
