im getting this error.

It looks like your untitled2 is a script, not a function, hence cannot be evaluated by feval. To define a function, you need to have, e.g.

function y = foo(x)

in your foo.m as the first line and then you can do

y = feval(@foo,x)

This may be a confusion with rows and columns. E.g. this code here fails:

a=[1 2 3 ]
a(1:2, :)

Beacuse a is an 1x3 matrix and a(1:2, :) tries to access a nonexisting second row.

MATLAB: How to access subfunctions from outside the main function in MATLAB

The ability to access subfunctions from outside of a function file via an "include" functionality is not available in MATLAB.

To work around this issue, a main function can provide a structure of subfunction function handles as an output argument. As an example, modify the function "foo1" as follows and save it in a file named foo1.m:

function fun_api = foo1
       fun_api.foo2 = @foo2;
       fun_api.foo3 = @foo3;
function foo2
       disp('in foo2');
function foo3
       disp('in foo3');

Subfunctions foo2 and foo3 can now be called from outside of foo1.m in the following manner:

fun_api = foo1;
fun_api.foo2();
fun_api.foo3();
