Assign separate handles to function outputs

I have a function that returns two outputs, the function value and its derivative. I'd like to create separate handles to the function value and the derivative. Is this possible?
For clarity, I'd like to do something like this:
function [f, fdx] = get_values(x)
...
end
f = @(x) get_values(x) %first output
g = @(x) get_values(x) %second output somehow, not sure how to do this

Create an additional function
function fdx=get_fdx(x)
[~,fdx]=get_values(x);
end
and now
f = @get_values%first output
g = @get_fdx %second output somehow, not sure how to do this

If you return the arguments as structure fields,
function out = get_values(x)
....
out.f=f;
out.fdx=fdx;
end
then you can do things like,
f = @(x) getfield(get_values(x),'f') %first output
g = @(x) getfield(get_values(x),'dfx') %second output
