is it possible to generate pareto front for 3 objective functions using GAPLOTPARETO in MATLAB? what about drawing first and third objective function pareto front instead of the 2 first objectives by using GAPLOTPARETO?

I'm asking myself that same question. When looking at gaplotpareto, it's obvious, that the function is capable of producing 3D plots when treating an optimization problem of equivalent order, since the 'plot3' function and a variable called 'plot3d' appear inside the code.
However, the first comment line of the function says "GAPLOTPARETO Plots a Pareto front for first two objectives."
Maybe someone else can clarify this. Thanks!

Without guaranteeing anything, I think you can plot any two objectives using the syntax
objectivesToPlot = [1,3]; % or whatever two objectives you want
plotfn = @(options,state,flag)gaplotpareto(options,state,flag,objectivesToPlot);
options = gaoptimset('PlotFcns',plotfn);
For three objective functions in a 3-D plot, try setting
objectivesToPlot = [2 4 7]; % or whatever you want
Please let me know if it works for you. If so, maybe I should document it.

I think that the topic Plot 3-D Pareto Front addresses this question.

In my case, the suggestion needed a minor fix:
options = gaoptimset(options,'PlotFcns',plotfn);
