A strange syntax in the code
hi guys, i met a very strange code in some paper.
function output = mymle(logdensity,x,del,param0,varargin)
objfun = @(param) (-logdensity2loglik(logdensity,x,del,param));
....
is any one know what this mean.
the matlab i use is

objfun is an anonymous function. Anonymous functions were introduced in
MATLAB 7.0 (R14) and so will not work in the version you have. You will
need to use another approach to define the objective function.
