Martin,

You're not very specific about your input data, but from what you write
it seems like
- your data are regularly gridded,
- you know beforehand how many rows and columns your 2D array will
have,
- the values in Arr1 are monotonically increasing or decreasing,
- the values in Arr2 are monotonically increasing or decreasing
for each set of triples with a given value of Arr1.

In that case, a solution of the problem might look like this:

nx = N_ELEMENTS(arr1) ; Number of columns in 2D array
ny = ... ; Number of rows in 2D array

result = FLTARR(nx, ny) ; Make 2D array
result[*] = arr3 ; Fill 2D array

Whether it is the shortest, fastest, most elegant, or whatever
solution, I don't know, but it should work.

Hope this helps,
Timm
