vin=linspace(0.2,2.8);

if vin < 0.5

current=0;

elseif 1.5 > vin >= 0.5

current=(860*10^-6)*(vin-0.5).^2;

elseif 2.5 > vin >= 1.5

current=(860*10^-6)*(2*(vin-0.5)*0.049-(0.049)^2) ;

elseif vin >= 2.5

current=(860*10^-6)*(2*(vin-0.5)*0-(0)^2) ;

end

plot(vin,current)

---------------------------------

Above is the code and hoped that make it into divided 4 part. (current versus vin)

but it has errors and could not catch how can mend it.

More like this

vin=linspace(0.2,2.8);
current = zeros(1,numel(vin));
for i = 1:numel(vin)
    v = vin(i);
    if v < 0.5
    current(i)=0;
    elseif 1.5 > v && v >= 0.5
    current(i)=(860*10^-6)*(v-0.5).^2;
    elseif 2.5 > v && v>= 1.5
    current(i)=(860*10^-6)*(2*(v-0.5)*0.049-(0.049)^2) ; 
    elseif v >= 2.5
    current(i)=(860*10^-6)*(2*(v-0.5)*0-(0)^2) ; 
    end
end
plot(vin,current)
