We made a basic function code but for some reason it's giving "ans" value as sayi1+sayi2(toplam)
How can i prevent the creation of the "ans" ?
Heres the code:
function [toplama, cikarma, carpma, bolme, ortalama] = hesap_makinesi(sayi1,sayi2)
toplama=sayi1+sayi2
cikarma=sayi1-sayi2
carpma=sayi1*sayi2
bolme=sayi1/sayi2
ortalama=(sayi1+sayi2)/2
end
Output:
>> hesap_makinesi(6,2)
toplama =
8
cikarma =
4
carpma =
12
bolme =
3
ortalama =
4
ans =
8

When calling a function with multiple outputs without specifying the outputs, only the 1st output is returned. And as you have not defined which variable to store the (first) output in, MATLAB uses "ans" as the variable name (by default).
You can prevent that by suppressing the call via a semi-colon -
hesap_makinesi(6,2);
toplama = 8
cikarma = 4
carpma = 12
bolme = 3
ortalama = 4
function [toplama, cikarma, carpma, bolme, ortalama] = hesap_makinesi(sayi1,sayi2)
toplama=sayi1+sayi2
cikarma=sayi1-sayi2
carpma=sayi1*sayi2
bolme=sayi1/sayi2
ortalama=(sayi1+sayi2)/2
end

Alternatively, you can return ouputs only when they are requested.
Use nargout to determine how many outputs were requested.
function [toplama, cikarma, carpma, bolme, ortalama] = hesap_makinesi(sayi1,sayi2)
if nargout > 0
toplama=sayi1+sayi2;
end
if nargout > 1
cikarma=sayi1-sayi2;
end
if nargout > 2
carpma=sayi1*sayi2;
end
if nargout > 3
bolme=sayi1/sayi2;
end
if nargout > 4
ortalama=(sayi1+sayi2)/2;
end
end
Demos
hesap_makinesi(6,2)
toplama = hesap_makinesi(6,2)
toplama = 8
[toplama,cikarma] = hesap_makinesi(6,2)
toplama = 8
cikarma = 4
[~, ~, carpma] = hesap_makinesi(6,2)
carpma = 12
[~, ~, carpma, ~, ortalama] = hesap_makinesi(6,2)
carpma = 12
ortalama = 4
