Why won't this equation plot?

Hey everyone I'm trying to get this code to plot the equation 'os' but it won't output anything onto my figure. Thanks for any help or suggestions, I appreciate it!

 z=0.1:.05:.9;                                
 os = 100*exp(-pi*z/(1-z.^2).^(1/2));
 plot(z,y);

You need to vectorise your os assignment, then you have to tell plot to plot ‘os’ rather than ‘y’:

z=0.1:.05:.9;
os = 100*exp(-pi*z./(1-z.^2).^(1/2));
plot(z,os)

Wow, I forgot to vectorize before dividing. Thanks for catching that for me!
