How do I make this script into a function?

%This program is a Slope Calculator.
%This program will calculate the slope in degrees from percent slope

disp('Would you like to calculate the internal angle?')
x = input('Please input rise/run as the gradient: ');

deg = (180/pi)*atan(x/100);
disp(deg)
end

Just before all of that, add the line

function SlopeCalculator

where the word SlopeCalculator must be the same as the base name of the .m file it is stored in.

Thanks! Doesn't it also need a function x= , or something like that as well ?

[Walter Roberson]

No. It is not required that functions return values.

If you happen to want to return deg then you could use

function deg = SlopeCalculator
