outputFcn_global

OutputFcn for Matlab Optimizers to capture intermediate optimization results.

outputFcn_global()

OutputFun for optimizers (fminunc, fmincon etc), saving intermediate results
in global variable "outputFcn_global_data" for later access.

It is not supposed for live updates during optimization but for
later inspection, which is much more efficient.

Usage
options = optimoptions( ... , 'OutputFcn',@outputFcn_global );
[XOpt,fval,exitflag,output] = fminunc(@fun, X0, options);
outputFcn_global_data(k).x
