What is the best way to rotate a 3D dataset about the Y axis

I would like to know the best way to rotate a 3 dimensional look up table dataset (Z as a function of X and Y) about the Y axis, so that X can be described in a look up table as a function of Y and Z. In particular, the new Z axis (now independant) needs to be generated as a uniform axis based on the non-uniform data.

Is it guaranteed that for each specific y, that each z will be produced by a unique x?

[Walter Roberson]

Do you require a particular interpolation function, or can we choose one that makes the coding easy?

I'm not entirely sure what is meant by the "guaranty for each specific y, that each z will be produced by a unique x" - but I will say that for each point on the new y and z independant axis, there is only one x (the surface remains a function).

I do not require any particular interpolation function, actually linear would be preferred.

Use the ROTATE function. For help on how to use the function, type:
