Basically, I need a UDF for 3D Interpolation.
I was able to make UDF for 2D Interpolation, but 3D is very difficult.
Scenario: I will have a table with X, Y, Z
and appropriate value f(x,y,z). With given table, if I pick any number to X,Y,Z , then interpolated f(x,y,z) is generated.
I attached a file! so please have a look!
My table will be either Table 1 or Table 2 or anything else.
Means, Range Y wouldn't be same, Interval wouldn't be same, etc.
Thank you in advance!
