Help for engineering equations

Hello i want to solve this equation in which diffrent set of values needs to be selected upon finding specific physical property. I am unable to correlate the logic.

The logic sounds simple. LHS (theta) can be any physical property like critical temperature, critical pressure, boiling point temperature and critical volume; for each of these property the contants a to f are given in table. You need to just substitute molecular weight, M.

M = 44.01 ;     % Co2 molecular weight 
gama = 1.53 ;   % specific gravity of co2 
K = [544.4 0.2998 1.0555 -1.3478*10-3 -0.61641 0.0 
    4.5203*104 -0.8063 1.6015 -1.8078*10-3 -0.3084 0.0 
    1.206*10-2 0.20378 -1.3036 -2.657*10-3 0.5287 2.6012*10-3 
    6.77857 0.401673 -1.58262 3.77409*10-3 2.984036 -4.25288*10-3 ] ;  % Table 1-4
a = K(:,1) ; 
b = K(:,2) ; 
c = K(:,3) ; 
d = K(:,4) ;
e = K(:,5) ;
f = K(:,6) ; 
theta = a.*M.^b.*gama.^c.*exp(d*M+e*gama+f.*M*gama) ;

theta would be a 4x1 array giving you critical temperature, critical pressure, boiling point temperature and critical volume respectively.
