Black Body and plotting

Hi, everytime I run the following programme no plot comes up - grateful for any idea? I eventually need to build a programme to fit the planck function to a black body, any tips gratefully recieved.

W =[0:1:3000];

t=6000;

f=((1.19104*10^(-16))/(W^5))*(exp(0.014387769/(W*t))-1);

plot(W,f)

Thank you for reply - the plot comes up now - but does not have anything actually plotted - any ideas why?

Check the formula, check the values..
