Dear all fellow community,

I'm curious about Matlab can read the 'dataBefore' and 'dataAfter' from .mat file with the current data display. I've tried many ways to get the data before and after. The data before and after will be used in the calculation in the 'MATLAB FunctionFever' block. Has anyone done this before?

The picture shows the Simulink block diagram of my work. As you can see in the 'simulation stop time', if I insert the value of 24, the display will display the data that has been stored in sensor1.mat at time=24.

Here is the beginning code that I can do to call the data before and after.

function bbtData  = detection(t)
bbtData = t;
end

For more info here I attach my work.

I hope for anyone to assist me in this problem. Thank you.
