Apply function to vector

For convenient reasons to plot functions I would like to apply a function to a vector:


x = 0:1:2*pi
y = sin(x)

So far, everything works fine.
But if I want to apply one of my functions the same way,

x = 0:1:40
y = rayleigh_optical_density(x) %contains just some simple calculations

I get the following message:

error: for A^b, A must be square

I read about element-wise operations, but I guess this is of no use here, isn't it?

Can someone tell me what causes the problem?

Kind regards,
