I am trying to make a for loop that would help me generate a polyfit to a data I have:
>> polyfit(T(x,y,z),z/30,8)
x goes up to 240
y goes up to 320
z goes up to 1500

It isn't obvious what you are trying to do, you have a 3D function and want to fit an order 8 polynomial to it in z only?
  1. In case you want to fit a 240 by 320 array of polynomials for every single slice through that array, loop over the x and y positions
  2. In case you want to fit a 3 D polynomial you might want to look at https://www.mathworks.com/matlabcentral/fileexchange/34765-polyfitn
