Interpolate2D.vi Help

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.
