[pstricks] Hyperbolic Paraboloidal for Rafael's Thesis

[Rafael Castro Triguero]

Hello PSTricks users,

My name is Rafael and I am doing some pictures for my PhD Thesis about 
hyperbolic paraboloidal  surfaces (I attached a .png example of an 
article). I uses these package and the commands for the picture are 
listed below. What kind of problem do I have? I have worked with 
Herbert  book and I have applied it but the program not run. Lot of 
thanks for your help.
