[ncl-talk] Interpolation error using linint1_n

[Giorgio Graffino]

Dear NCL people,I want to report a (potential) error in the documentation.
While looking at how to interpolate a monotonically decreasing dimension from a 2D variable onto another, I found the linint1 functions (https://www.ncl.ucar.edu/Document/Functions/Contributed/linint1_n.shtml). It is said that the relevant dimension "must be strictly monotonically increasing or decreasing". However, when I run the function no output variable is created and the following warning appears
 warning:linint1_n: xi and xo must be monotonically increasing
I'm using NCL 6.3.0 (quite old, I know) on a Linux cluster. Could it be the reason why a monotonically decreasing dimension is not accepted? Or is the documentation wrong?

Cheers,Giorgio
