How to define if variable with one unknown parameter

Hi,

Working with the JONSWAP spectrum, with an unknown frequency f and a known frequency fp

Sigma value is depending on the relation between f and fp.

If f is smaller or equal to fp, then sigma = 0.07

If f is larger than fp, then sigma = 0.09

Could someone explain how to perform this is in Matlab?

The easiest way:

sigmafun = @(f,fp) [(f <= fp)*0.07 + (f > fp)*0.09];

sigma1 = sigmafun(1,2)          % Test Calls
sigma2 = sigmafun(2,1)
sigma3 = sigmafun(3,3)

Thank you @Star Strider.
