I'm not clear on your question.

Multidimensional arrays are easily created in Octave, but are  
generally not needed to produce 3D plots. See the link below.

http://www.gnu.org/software/octave/doc/interpreter/ 
Three_002dDimensional-Plotting.html#Three_002dDimensional-Plotting

For example, using 1D vectors.

z = (0:200)/100;
x = z.*(2-z).*cos (8*pi*z);
y = z.*(2-z).*sin (8*pi*z);
plot3 (x, y, z)

Contours are generally produced using 2D input data (see the link  
above).

What type of 3 D figures are you looking to produce?
