Problem 4.21 from Matlab: A Practical Introduction to Programming and Problem Solving. Attaway

I am supposed to write a function to receive the temperature and wind speed as input arguments, and return the wind chill factor. Using loops, I need to print a table showing wind chill factors for temperatures ranging from -25 to 55 in steps of 5, and wind speeds ranging from 0 to 55 in steps of 5. Last of all I need to call the function to calculate each wind speed.

I am given the function for the wind chill factor as: 35.7 + 0.6 T - 35.7(V^0.16) + 0.43T(V^0.16) where T is the temperature and V is the velocity of the wind.

windchill = @(T,V)bsxfun(@(T,V)35.7+0.6*T-35.7*(V.^0.16)+0.43*T*(V.^0.16),T(:),V(:)'); %function to get windchill factor
wcf = windchill(-25:5:55,0:5:55); %called with desired inputs
