I have a parameter or a variable (T) which should increase or decrease with a (delta_T) and it has an initial value of (T_0).
So, I defined (delta_T = ....) and (T_0 = 20) and it should be a loop (T = T + delta_T) which updates the value of T each time step.
I will put this function in a block in Simulink.
I hope my question is clear and many thanks in advance.

I have tried the following but failed to update T
function [delta_T,T] = fcn(u)
m=100;
T = 20;
delta_T = u/m;
T_max = 100;
while T <= T_max
T = T + delta_T;
end

Use the "Ramp" block to generate such a signal.
