nu = 1.5e-5;
ya = 9.7;
k = 0.41;
y = 2.3025e-03;
uT = (k.*rho.*nu).*((y.*ustar/nu) - ya.*tanh((y.*ustar/nu)/ya))

From equation standpoint, the formula is correct. Apart from what Steven has mentioned below, are you facing any other problem?

Nowhere in this code do you define the variables rho or ustar.
