OK, I see > that is most likely what you meant. yes, it would still be a vector class, so a 1 by 2 matrix (or array) would still act like a 2-d object. The only issue here is if you need a separate "row vector" and "column vector" class -- I think it's a matter of what whether these vectors are special versions of 1-d arrays or 2-d matrices. I kind of like them as special versions of 1-d arrays, as a vector is a 1-d object, but I see that the implementation is a bit cleaner if you just make them 2-d matrices with a different scalar indexing. -Chris -- 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 [EMAIL PROTECTED] _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
