MATLAB: Function using if or switch statement

if statementMATLABmatlab functionswitch statement

I am going to make a function called XYZ that takes as its only input argument one positive integer specifying the year of birth of a person and returns as its only output argument the name of the generation that the person is part of ('X', 'Y', or 'Z ') according to the table below. For births before 1966, return 'O' for Old and for births after 2012, return 'K' for Kid . Remember that to assign a letter to a variable, you need to put it in single quotes,
I have make that code
    function born=generationXYZ(n)
    if 1966<=n<=1980
        born='X';
    end
        if 1981<=n<=1999
            born='Y';
        end
            if 2000<=n<=2012
               born='Z';
            end
            if n<=1966
                born='O';
            end
            if n=>2012
                born='K';
            end
        end
but when i test this code i getting an error when i remove last two if check i always recipe z in output.
I know it can make with switch statement kindly refer me where i need corrections. Thanks in advance for assistance….

To fix your code, use Walter's answer.
You call also altogether avoid if or switch and use:
function born = generationXYZ(n)
   bins = [-Inf, 1966, 1981, 2000, 2013, +Inf]; %as Walter pointed out some of your edges are ambiguous
   gennames = 'OXYZK#'; %return # if input is +Inf
   born = gennames(discretize(n, bins));
end
This also has the advantage that it also works for vectors
