How would I output the 'ans' as 'TaxPayable' instead?

Hi, how would I output the 'ans' as 'TaxPayable' instead. I'm also aware that this code is probably very inefficient, so any suggestions wouldn't go a miss. How would I also get a '£' symbol in front of the value after 'ans'? Thank you!

    function [TaxPayable] = TaxCalculator(AnnualSalary, Year)
%The first if statement looks if the input Year is valid, if not it
%displays an error message.
if Year == 2015 || 2016 || 2017 %If the input year is valid, the function will use the correct year
    if Year == 2015
        if AnnualSalary >= 43352 %The function then finds the correct salary range
            TaxPayable = 6690.4 + (AnnualSalary - 43352)*0.4; %Once in the correct salary range it uses a
        elseif AnnualSalary>=11000                            %predetermined figure plus the amount of money
            TaxPayable = 220 + (AnnualSalary-11000)*0.2;      %over the tax bounds.
        else 
            TaxPayable = 0.02*AnnualSalary;
        end
    elseif Year == 2016
        if AnnualSalary >= 43352
            TaxPayable = 5127.8 + (AnnualSalary - 43352)*0.45;
        elseif AnnualSalary>=11000
            TaxPayable = 275 + (AnnualSalary-11000)*0.15;
        else 
            TaxPayable = 0.025*AnnualSalary;
        end
    else
        if AnnualSalary >= 43352
            TaxPayable = 8088 + (AnnualSalary - 43352)*0.48;
        elseif AnnualSalary>=11000
            TaxPayable =(AnnualSalary-11000)*0.25;
        else 
            TaxPayable = 0*AnnualSalary;
        end
    end
else
    disp('Error, invalid year')
end
end

I get the impression that you are calling it as:

TaxCalculator(AnnualSalary, Year)

without an output variable. Calling it instead as:

TaxPayable = TaxCalculator(AnnualSalary, Year)

will probably do what you want.

Ah, got it!

Great!

Some things are not always obvious.
