how to declare

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));

Thanks, its working.
