Wind Farm Turbine Layout

I am trying to create a model of a wind farm using a grid matrix of wind turbines. How can I create a function which I can enter the direction of the wind, which alters the power production of each turbine and has an effect on the wake of each turbine? Here is a sample of my code to create the farm layout:

wf = zeros(5,5); wf(1,1) = 1; wf(2,2) = 2; wf(3,3) = 3; wf(4,4) = 4; wf(5,5) = 5; wf(2,4) = 6;

The nodes represent the location of a turbine in the 5x5 matrix. So for example, how do I create a variable for wind which comes at an angle of 190 deg?
