express function as function handles

How can i express this function as a function handle @dints

function f = dint2(x, y)
    tmp=[];
    for ii=1:1:length(x)
        tmp(ii)=x(ii) * y^2 *density(x(ii),y);
    end
    f=tmp;
end

It would be more efficient to initialize

tmp = zeros(1, length(x));

See Create Function Handle and try

fh = @dint2;

What's density() ?
