f(x,y,z) to wave

Hallo.

I'm beginner in Igor Pro. Sorry, for probably simple question.
I have 4 1D waves: x-coordinate, y-coordinate, z-coordinate, and intensity which is function of x, y, z. How I can convert these waves in single wave f(x,y,z)?
Thanks for your help.
Use the Concatenate operation:
Concatenate/O {xwave,ywave,zwave,intensity},wdest  // wdest is a 10x4 matrix
