Hello guys, I'm trying to get the closest or equal value to an specific value that's in a 2D array I also need to find the line number where this value is How can i find the value and the index of the row of this value?

"Array Max & Min" can find the smallest difference. Also, most of these math nodes work with N-dim arrays.

LabVIEW

Find the closest number from 2D array

Solved!

I think you're right, because the 1D array isn't guaranteed (or required IIRC) to be ordered.

The help says "non-descending"., but I don't understand the 2D part: Must be some math lingo.... 😄

Never though about reading the help 😋.

In my defense, it now takes 45 sec. to open the online help. I sometimes open an old LV version to get easy access to the 'fast' help.

The '2D' doesn't refer to the array dimension, but to the data space of the graph.

The 1D array can represent X, Y points (iff it's a 1D array of clusters, see "array of numbers or points"). Those points represent a 2D data space (in a 1D array).

If the input array is a 1D array of doubles (the Y values), the indices are the X values, and those X, Y values also represent a 2D data space with connected points (a graph).

Wording could be clearer.
