Calculate function in matlab

Question

is there any way to calculate a function in matlab using toolbox? for example I have this function: f(x,y)=x^2+y^2, I want to set x=2 and y=2 and function take back 8. How can I do it? Thanks

The keyword you are looking for is `function handle`. Feel free to add `MATLAB` into it. — Divakar, May 22 '14 at 07:00

you can use anonymous functions, for example:

f=@(x,y)x.^2+y.^2;

or just write a file for example abc.m that has this code:

 function f=abc(x,y)
 f= x.^2+y.^2;

then abc(2,2) will return the answer if the function file is at the path.

This is good, takes care of any sized arrays, not just scalars. – Divakar May 22 '14 at 07:03

You can use anonymous functions:

>> f = @(x,y) x^2+y^2;
>> f(2,2)
