MATLAB: Extract Data from for loop

Question

I am attempting to plot SFC and TSFC vs The PRC values based on each value of Mach. I am trying to find a way to extract all calculated values of SFC and TSFC from the for loop for plotting. Any help would be appreciated

      U = Mach*sqrt(gamman*R*Ta);
      Toa = Ta.*((1+(((gammad-1)/2).*(Mach^2)))); 
      To2 = Toa; 
      To2sTa = (1+((etad.*((To2./Ta)-1))));
      Po2 = Pa.*((To2sTa).^(gammad/(gammad-1)));
      for PRC = 5:5:100
          Po3 = PRC.*Po2;
          To3 = To2.*(1+((1./etac).*(PRC.^((gammac-1)/gammac))-1));
          for To4 = [1500 1600 1700]
              Cpb = ((R*gammab)/(gammab-1));
              f = ((To3.*((To4./To3)-1))./((QR/Cpb)-To4));  
              Po4 = Po3;
              To5 = To4-To3+To2; 
              Po5 = (Po4.*(1-(1./etat)*(1-(To5/To4))).^(gammat/(gammat-1)));
              U7 = sqrt((2*etan*R*(gamman/(gamman-1)))*To5*((1-(Pa/Po5)).^(gamman-1/(gamman))));
              SFC = ((1+f)*U7-U)/1000; %((kN*s)/(kg))
              TSFC = f*SFC; %((kg)/(kN*s))
          end
      end
end

Answer 1

After

SFC = ((1+f)*U7-U)/1000; %((kN*s)/(kg));

Use

SFC = [[];SFC];

But define

SFC = [];

Before loop

Same for TSFC
