Hi,
yes it should be possible but its better to create some Anonymous Functions instead of using inline, e.g.
f = cell(10,1);
for i=1:10
f{i} = @(x) x*i;
end
The output of f looks a bit strange because it seems to be the same function handle all the time, but it isn't:
>> f{1}(1)
ans =
1
>> f{2}(1)
ans =
2
>> f{3}(1)
ans =
3
>> f{3}(4)
ans =
12
Or:
f = cell(2,1);
for i=1:2
tmp = inputdlg('enter function handle')
f{i} = eval(tmp{:})
end
And enter things like:
@(x)x^2
@(x)x-3
Make the call to eval fail proof!!

There is no need to hit it with the evil eval hammer, str2func seem perfectly designed for this purpose with hopefully a lot less side effects

You need to zuse {} instead of () when you call eval. inputdlg gives back a cell. Also don't use i to index into it. This should work:
f{i} = eval(user_input{1})
