To see the intial population, one can specify or set the 'OutputFcns' property from the option used by GA. The function set by 'OutputFcns' gets called every itteration.
First write a function MATLAB file called my_view containing
function [state, options,optchanged] = my_view(options,state,flag,interval)
optchanged = false;
disp(state.Population)
end
Now set the 'OutputFcns' property to this function via
options = gaoptimset('OutputFcns',@my_view);
Finally call the GA function with this specified option
x = ga(fitnessfcn,nvars,options)
