Or maybe I'm totally missing the point. But anyway, are (N,1) and (1, N) arrays insufficient for representing column and row vectors for some reason? If not -- then we have a way to express a column or row vector, we just need an easier and more obvious way to create them. *maybe* we could have actual column and row vector classes -- they would BE regular arrays, with (1,N) or (N,1) dimensions, and act the same in every way except their __repr__. and we're provide handy factor functions for them. These were needed to complete the old Matrix class -- which is no longer needed now that we have @ (i.e. a 2D array IS a matrix) Note: this is not very well thought out! -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov
