generalize a function according to input
显示 更早的评论
Hi, i need your suggestion about generalize a code for each variable. For example, i have a code, but it is special for x. I have a function like f(x)=x.^2-3*x+5; and this code generate f(x) according to x. I want to generalize code for x,y,z,... and more variable, for example if my function is f(x,y)= x.^2-2*y+6, i want code to work for x and y variable.
So i need some beginning suggestions, i'm in searching process. Thank you.

Is the function you are trying to generate always a mathmatical function? Further, is it allways polynomial?

You can try using varargin, which allows functions to take a variable number of inputs.
function result = f(varargin)
Inside your function, use nargin or the length of the varargin cell array to determine the number of function inputs. From there, use if statements to specify what do to for each case.
if nargin == 1
x = varargin{1};
x.^2-3*x+5;
elseif nargin == 2
