I wrote a code to do something and this code contains bunch of if statements and other things. when i try to run the program i face this error

 ???     DeagPGA2475((ceil(2*aa)-(2*Mmin)),round(((R/10)+0.5))=Ny+DeagPGA2475((ceil(2*aa)-(2*Mmin)),round((R/10)+0.5));
                                                                    |
Error: The expression to the left of the equals sign is not a valid target for an
assignment.

and my complete if statement is

 if o==1
          if (R-floor(R))<=10
             DeagPGA475((ceil(2*aa)-(2*Mmin)),round((R/10)+0.5))=Ny+DeagPGA475((ceil(2*aa)-(2*Mmin)),round((R/10)+0.5));
           elseif (R-floor(R))>10 & R<=200
            DeagPGA475((ceil(2*aa)-(2*Mmin)),11)=Ny+DeagPGA475((ceil(2*aa)-(2*Mmin)),11);
           else
            DeagPGA475((ceil(2*aa)-(2*Mmin)),12)=Ny+DeagPGA475((ceil(2*aa)-(2*Mmin)),12);
          end
         elseif o==2
          if (R-floor(R))<=10
           DeagPGA975((ceil(2*aa)-(2*Mmin)),round((R/10)+0.5))=Ny+DeagPGA975((ceil(2*aa)-(2*Mmin)),round((R/10)+0.5));
          elseif (R-floor(R))>10 & R<=200
           DeagPGA975((ceil(2*aa)-(2*Mmin)),11)=Ny+DeagPGA975((ceil(2*aa)-(2*Mmin)),11);
          else
           DeagPGA975((ceil(2*aa)-(2*Mmin)),12)=Ny+DeagPGA475((ceil(2*aa)-(2*Mmin)),12);
          end
         elseif o==3
          if (R-floor(R))<=10
