Transfer Curve in Matlab

Here you have a help for do the program of a FET transfer curve this one is based on matlab, you have to make it in other languaje as Visual B, C#, etc.

Channel N
Idss=8; constant you have to give this value
Vp=-6;
Vgs=(Vp:0.1:0);
Id=Idss*((1-(Vgs/Vp)).^2);
plot(Vgs,Id)

Channel P
Idss=8
Vp=6
Vgs=(0:0.1:Vp)
Id=Idss*((1-(Vgs/Vp)).^2)
plot(Vgs,Id)

As you can see is not that hard only requirs 5 lines.
