Hi Guys,
I have a homework I have to use valuable that ı defined with numbers like A=0.5..C= 0.3. Users can choose these variable when ı ask to user that vehiclename=input('please enter the veicle name such as A,B,C). If user respond C, the vehiclename will change to value of the C like 0.3.
VehicleName = input('please enter the vehicle name');
if if VehicleName= A || a;
VehicleName = 0.5;
elseif VehicleName= B || b;
VehicleName= 0.4;
elseif VehicleName= C || c
VehicleName= 0.3;
end
You see what ı can do please could you help me ?

vn = input('please enter the vehicle name ','s');
switch upper(vn)
case 'A'
val = 0.5;
case 'B'
val = 0.4;
case 'C'
val = 0.3;
otherwise
error('this vehicle type is unknown')
end
