plotting in matlab what should i do?

I want to plot x vs w, from the following code, but I'm not getting the correct plot. Could you explain it for me??

function[x]=packegingsystems(w,k1,k2,d)
if w<(k1*d)
    x=w/k1;
else
    x=(w+2*k2*d)/(k1+2*k2);
end
display(x)

and my attempt to plotting it:

w=linspace(0,3000,300)
x=packegingsystems(w,1e4,1.5e4,0.1)
plot(w,x)

This is not correct, the plot should consist of two ranges; as defined in the function file.

Try this:

function x = packegingsystems(w,k1,k2,d)
x=(w+2*k2*d)/(k1+2*k2);
indexes = w < (k1*d); % Logical index.
x(indexes) = w(indexes) / k1;
