I have prepared a code in MATLAB with optimization toolbox which seems to be giving fair results for different optimization functions but at present, accuracy is highly dependent on the type of crossover selected.
To take advantage of different crossover and to improve efficiency, i want to apply a random crossover after every iteration i.e. any of Arithmetic, Scattered or Two-point. How can I do that ?

options = optimoptions(options,'CrossoverFcn', @MyCustomCrossover)
function varargout = MyCustomCrossover(varargin)
crossfcns = {@crossoverarithmetic, @crossoverheuristic, @crossoveritnermediate, @crossoverscattered, @crossoversinglepoint, @crossovertwopoint};
chosen = crossfcns{randi(length(crossfcns))} ;
[varargout{:}] = chosen(varargin{:}) ;
end

See the screen shot given in the attachement. You should select from the drop-down options whichever crossover function suits for your task.

I show using a literally random crossover in https://www.mathworks.com/matlabcentral/answers/577609-how-to-apply-a-random-crossover-arithmetic-scattered-two-point-in-genetic-algorithm-using-auto-gen#comment_968707
