suppose i get a graph of variable vs time using scope in simulink..and i want to find the equation of the same....any command in simulink or matlab to get the equation in the form y=f(t)...

If you know the approximate form of the equation, you could use the Curve Fitting Toolbox, or possibly the System Identification Toolbox.

If you do not know the approximate form of the equation then there are literally an infinite number of different equations that would exactly fit all the data points.
