I have some outputs that I am plotting and I am wondering how I can smooth out the curves.

My model is calculating the clutch torques in a transmission during a 1-2 upshift event. Attached are plots of one of my outputs where one of them look good, clutch E, but that is a function of that clutch during the shift as it is on during the shift. I am having issues with the off going clutch, on going clutch and my torque out of the transmission.

How do I apply a smoothing function to these? Please help quickly! :)

Here is my code for the torque calculations.

function [Tout,Tc,Te,Tf,WDOTin] = Transmission_System(Tin,WDOTout,GEAR,Vs)

Just a comment:

elseif (Vs>=8.046)&&(Vs<=9.387)
  ...
elseif (Vs>=9.387) ...

You have tested for Vs<=9.387 in the first elseif already. Then it cannot be == 9.387 in the 2nd elseif . You can even omit the complete test to Vs>=9.387 , because this must be true already after the former tests.
