how to calculate a row of number to be calculate in if else statement matlab

%example of energy consumption

units=[0 800.09 364.73 776.42 695.21 698 338.67 498.05 426.35 713.48];

%units=EnergyConsumption;

result=0;

if units>900

result=units*0.571-118.3;

elseif(units>600)&&(units<=900)

result=units*0.546-95.8;

elseif(units>300)&&(units<=600)

result=units*0.516-77.8;

elseif(units>200)&&(units<=300)

result=units*0.334-23.2;

elseif(units>0)&&(units<=200)

result=units*0.218;

TotalBill=result

end;

units=[0    800.09  364.73  776.42  695.21  698 338.67  498.05  426.35  713.48];
results=zeros(size(units));
results(units>900)=units(units>900)*0.571-118.3;
results(units>600&units<=900)=units(units>600&units<=900)*0.546-95.8;
results(units>300&units<=600)=units(units>300&units<=600)*0.516-77.8;
results(units>200&units<=300)=units(units>200&units<=300)*0.334-23.2;
results(units>0&units<=200)=units(units>0&units<=200)*0.218;
TotalBill=sum(results);%I assume you want to sum results
