Can Octave solve this kind of numerical analysis problem ???

[Ramesh S Guzar]

Hi,

I have a problem which is related to the numerical analysis.
Hence I thought I would seek your help on this.

I have a Parameter "Z" which depends on 5 independent variables
l, m, n , o and p.
A1, A2 ......An are the values of Z for (l1,m1,n1,o1,p1) .....
to (ln,mn,nn,on,pn) co-ordinates.

Pictorially, the above looks like,




        ^ Z
        |               A2    . .  . . . .  An
        |      A1 . . . . . . . . .. . A3
        |               A32     A29 . . . . 
        |               
    n   |   m           A5      A6      
     \  |  /     
      \ | /          A7......A8
       \|/
        *-------------------------------->l
       / \
      /   \
     /     \
    o       p


Is it possible to fit a curve or get an expression for "Z" interms
of the know points like A1,A2.....An, and interpolate the value
of "Z" for any (l,m,n,o,p) set ? Can Octave do this ? If not 
directly, do you have any suggestions on how to use Octave to 
solve this problem ? 

I would highly appreciate any help on this problem.

Thanks and best regards,
Ramesh
