if there is a funciton like f(i,j)=i+2*j
and I have already print out a 3D picture use the commend
"plot3d(f,i=1..10,j=1..10);"
the 3D picture just like the link : http://imgur.com/eLYhYEs
how can I convert the datas in 3D picture to text file?
the type may be like as follow I think.
-------------------------------------
(i,j)=f(i,j)
(1,1)=3
(1,2)=5
(1,3)=7...
-------------------------------------
I had try
"writedata("C:\\desktop\\a.txt",3Ddatas)"
but it seems can only output one variable parameter in a function, what else can I do?
thanks a lot.
