Output argument 'ledval1' is not assigned on some execution paths.

here is my code:- function [ledval1,ledval2,ledval3]= checkTorque(Torque) if Torque < 100; ledval1 = led.RED; else if 50 <= Torque < 80; ledval2 = led.YELLOW; else ledval3 = led.BLUE; end end

Yes, you have three output values - ledval1,ledval2,ledval3. for example, if torque is 60, only ledval2 is assigned. Other two outputs are not assigned.

1. You can set all values to some default value before using if.

function [ledval1,ledval2,ledval3]= checkTorque(Torque)
ledval1='No Colour';ledval2='No Colour';ledval3='No Colour';
if Torque < 100; 
    ledval1 = led.RED; 
else
    if 50 <= Torque < 80;
        ledval2 = led.YELLOW; 
    else
        ledval3 = led.BLUE;
    end
end

or 2. Use one value as output.

function ledval= checkTorque(Torque)
if Torque < 100; 
    ledval = led.RED; 
else
    if 50 <= Torque < 80;
        ledval = led.YELLOW; 
    else
        ledval = led.BLUE;
    end
end

Thanks J Smith I already had second code,Problem is my code is in Simulink as Matlabfunction. but it is not taking some how torque value and that's why I am not getting LED Colors. If you have any idea about it, Please do help me.
