Which MATLAB version are you using? Is the error message pointing to a "~" character?

thanks alot for your answer. I'm using MATLAB 2013,totally i can not use this code so i tried to run the examples which exist in matlab user guid, the below code is an example of the codes which i tried:

plot(plot::Arc3d(1, [0,0,0], 0.1..2*PI-0.1, Filled,
     LineColor=RGB::Yellow, LineColor2=RGB::Red, LineColorType = Dichromatic, LineColorDirection=[+1,0,0],
     FillColor=RGB::Yellow, FillColor2=RGB::Red, FillColorType = Dichromatic, FillColorDirection=[-1,0,0]
))
||      but the program shows this error:||
plot(plot::Arc3d(1, [0,0,0], 0.1..2*PI-0.1, Filled,...
         |
Error: Unexpected MATLAB operator.
and the error ''Error: Unexpected MATLAB operator.'' is general for all the examples, the follow link is the link of these examples.
