The above graph is the purpose that i want.
The below is the code and it has errors. Whats the problem? Please suggest the code. Thanks
--------------------------------------------------------------------------------------------------------
W=40;
Vth=0.45;
Leff=0.15;
k=4.255*(10^-4)*(W/Leff);
lambda=25*10^-5;
Vgs=linspace(0,2);
vds=[0.2 1 2];
m=length(Vgs);
for k1 = 1:numel(vgs)
for i=1:m
if vgs(k1) < Vth
current(k1,i)=0;
elseif Vds(i) >= (vgs(k1) - Vth)
current(k1,i)=0.5* k * ((vgs(k1) - Vth).^2);
elseif Vds(i) < (vgs(k1) - Vth)
current(k1,i)= k*((vgs(k1)-Vth)*Vds(i) - 0.5*(Vds(i).^2));
end
end
end
figure
plot(Vgs,current, 'LineWidth',1.5)

error: 'current' undefined near line 1, column 1
error: 'vgs' undefined near line 1, column 1

You have set Vgs with linspace but then refer to vgs in the code. This is possibly creating both errors as the current is calculated from 'vgs'
