I have plotted a velocity vs time graph for a car that uses a ramp input (with slope 5) as throttle input. Is there a way to calculate the slope (acceleration) from the plot in the simulink environment itself?

The slope of the velocity line needs to be used elsewhere in simulink when I use different slopes for the ramp input of throttle. Hence, your solution would help me use the slope data (acceleration) in my controller.
I have attached a matlab figure for reference.
Thank you in advance.

Hello Vishal,
First your image is showing error. If you want to find the slope of a curve, it can be found with the helpof desired points using the diff function or gradient method. Assume if you want to find slope of two points at A and B then slope at that instant is given as:
slope=diff(B)./diff(A).
