Hi All,
I would like to declare the following code in Matlab.
r = 4/pi atan((R-G)/(R+G))
Any one please help.
Thanks,
Pugazh

Do you have the symbolic toolbox? If yes than
syms R G
r = 4/pi * atan((R-G)/(R+G));
else you're more than likely going to hve to define R and G in terms of domains. For example
R = 0:0.01:1;
G = 0:0.1:10; %Make sure the matrix dimensions agree.
r = 4/pi * atan((R-G)/(R+G));
Matrix manipulation is what matlab was designed to do at its basic level. the symbolic stuff is an add on that works pretty well.

Probably you meant
r = 4/pi * atan((R-G) ./ (R+G));
