[LabVIEW] Interpolation of 2D array with 1D xi

[ILA-Reichstein]

I have a set of data similar to the following example:

001    5    2,35    1,45

002    -5  2,21     1,68

Now I have a given value xi for the third column, say xi=2,30

As this value does not match an entry in my list I want to interpolate. But not only do I want to interpolate column 3 but also the adjacent columns 2 and 4 respectively. The output of this routine should be an array like

1,43    2,3    1,53

Is there a nice and easy way of handling this w/o using many loops and a ton of functions?

Thanks a lot!

Hi,

I don´t think there is a ready to use solution fo your problem in LabVIEW.

But can you please explain more clearly, by using indices, what you try to do?

There a two function on the array pallete that work together.

Threshold 1D array and Interpolate 1-D array.

Slice out (index array) the collumn/rows you will use, use the Threshold then pass the fractional index to the Interpolate.

"Lather rinse repeat" (do it in a For loop with an auto-indexing output tunnel).
