Hi guys, i am trying to match a graph of my simulink model with a graph of a standarized model.
I have my lateral speed against time. This graph depends on a variable and the time. So with linear fitting i am getting two different polynomials(equations) to multiply to my graph to make it similar to the graph of the standarized model.
What i still dont know how to do is to code it. What i need to do is create a variable that changes its value(polynomial equation) for different time periods, so for example from the time 0 to 2, the variable will be a polynomial equation, and for the time 2 to 4 the variable will be other polynomial equation.
Regards,
Alejandro

Maybe something like this.
