I need help with using the If-Else loop containing scalar and nonscalar

Create a plot of iD as a function of vDS from 0 ≤ vDS ≤ 8 V, for three values of vGS =2, 3, and 4 V.
Constants: Kn=0.2 mA/V2; VTN =1.2 V; λ=0.01 V-1.
Here is my work I have so far:
Vds = 0:0.1:8;
Vgs = 2:1:4;
kn = 0.2;
Vtn = 1.2;
lambda = 0.01;
Vds_Sat = Vgs - Vtn;
if (Vds <= Vds_Sat)
ID = Kn*(2*(Vgs-Vtn)*Vds - (Vds^2));
else (Vds >= Vds_Sat)
ID = Kn*((Vgs - Vtn)^2*(1 + lambda * Vds));
end
plot(Vds.,ID)
It is telling me I have an error on line 7 and that my matrix dimension must agree, could you please help me with this?

There is no such thing as an "If loop". There is an "if statement". Loops execute the body multiple times; statements execute the body (or not) exactly one time.
