How do I perform the interp3 function in matlab in LabVIEW

I have the following data attached (DTTT.txt).  The four columns are as follows: Column 1, 2 and 3 are (fixed) measurement points and the fourth column is the resulting measurement data using these 3 points. What I need to do is find the value that should be in column 4 with the values in columns 1, 2 and 3 of (i.e. 0, 100 and 20).  Is there any base function in LabVIEW for performing this interpolation? I would be using interp3 in matlab for this, but we only want to use strict LabVIEW code in this project (i.e. no external interface to matlab allowed). Thanks for any help I can get...

There are quite a few interpolation functions in LabVIEW.

Go to

Function Palette


Mathematics Palette


Interp & Etrap Palette

and choose the VI that will work from there.
