[ncl-talk] functions handling input of unknown dimension

[Will Hobbs]

Hi all

I wonder if anyone has any suggestions for a generic way of writing functions that deal with input/output arrays which may have different numbers of dimensions, e.g.

function generic_example(input:numeric)

begin
  output = some_subset_of_(input)

  return(output)
        end

where input/output might be 1, 2, 3, 4 or more dimensions, and so a different line is needed to do the subsetting step.

At the moment I just use nested 'if' statements based on the rank of the array (where rank is the number of dimensions, i.e. dimsizes(dim sizes(input)), and this works fine. But, it does not make for particularly 'clean' or efficient code, so I wonder if anyone has any nicer ways of doing this.

Many thanks

Will
