MATLAB: How to merge function handles in matlab

Question

Hi!

I have a function handle of this form:

fk = @(a, b, k) a+b+k;

I would like to obtain another function handle that is actually a vector where every element is the first function handle evaluated in k, for k between 1 and a given n.

f = @(a, b) [fk(a, b, 1) fk(a, b, 2) ... fk(a, b, n)]

Example: for n =3, I would like to obtain

f = @(a,b) [fk(a, b, 1) fk(a, b, 2) fk(a, b, 3)]

How can I do this?

P.S.: I would like something that looks like a for loop, that can work for every given n.

Answer 1

You could use arrayfun for this:

fun = @(a,b,n) arrayfun(@(nn)fk(a,b,nn), 1:n);
