I want to use the value of one plot from simulink inside the matlab function block. For example for t>40, g_initial=g(40), where g(40) is the value of function g at time instant 40. Even at time instant 80, I want to use the same initial condition. But I am not able to do that.

Hi,
(1) You would need to simulate your simulink model inside your matlab script that can be done with sin() that you have probably employed already.
(2) Use the output values from your [Scope] or signal going to [Scope] via [To Workspace] block.
(3) Proceed with the acquired signal. Since you're intending to use specific values acquired from Simulink model that can be manipulated with logical indexing or conditional statement opeators, etc.

Hi,
if you have employed [To Workspace] block, you can use this syntax within your m-file:
OUT = sim('ABC.slx'); % Simulink model called ABC.slx and Output variable name: OUT
plot(OUT.tout, OUT.simout)
Good luck.
