How to merge values as given index in a single array
porindex1 = find(por<=0.47); %% por<=0.5porindex2 = find(por>0.47&por<=0.63); %% por>0.47& por<=0.63porindex3 = find(por>0.63);Sw1 =Sw(porindex1);Sw2 = Sw(porindex2);Sw3 = Sw(porindex3);Sg1 =Sg(porindex1);Sg2 = Sg(porindex2);Sg3 = Sg(porindex3); k_fl1 = ((k_water./Sw1) -k_co2).*(1 - Sg1).^(1.2) + k_co2; k_fl2 = ((k_water./Sw2) -k_co2).*(1 - Sg2).^(1.6) + k_co2; k_fl3 = ((k_water./Sw3) -k_co2).*(1 - Sg3).^(2) + k_co2; I want to merge the values of k_fl1,k_fl2, and k_fl3 values into a single array as k_fl via index position, which is defined by porindex1,porindex2, and porindex3.

porindex1 = por<=0.47; %% por<=0.5
porindex2 = por>0.47&por<=0.63; %% por>0.47& por<=0.63
porindex3 = por>0.63;
exponent = zeros(size(por));
exponent(porindex1) = 1.2;
exponent(porindex2) = 1.6;
exponent(porindex3) = 2;
k_fl = (k_water./Sw - k_co2).*(1 - Sg).^exponent + k_co2;
