[ncl-talk] Combine Array

[Walter Kolczynski]

Please always reply to the list and not to people individually.

Please make sure the arrays you are passing into array_append_record are 
the correct dimensionality. Looking at your example again, x1=a(0,:,:) 
will automatically remove the degenerate time dimension, reducing the 
rank from 3 to 2, so when you try to use array_append_record to combine 
with x2 (which is still rank 3), you get an error. You could use conform 
to add the extra dimension back on to x1, but a better way is still to 
give all the indexes you want at once:

inds = array_append_record( 0, ispan(2,29,1), 0 )
x = a(inds,:,:)

That way you keep all of the metadata.
