Hello,
I am trying to perform a 2D linear interpolation the following data:
30 50 70
55 1 2 3
75 4 5 6
95 7 8 9
I noticed that there is already a built in VI to accomplish this, but I am having difficulty using it. I understand what the Z, X, and Y arrays are, but am having problems with the xi and yi inputs. I don't want to input an array of values to interpolate, because I only want interpolation to be performed at a single point.
Any help is greatly appreciated.

Hi,
I believe a detailed explaination of the 2DINterpolat.vi is offered at the bottom of the page include in the linke below:
Interpolate 2D VI
After reviewing this document, please post any more specific questions you have regarding the function input/output?
Cheers!

Look at Altenbach's old thread. https://forums.ni.com/t5/LabVIEW/2D-Interpolation/m-p/232784
