So I guess it's the show's, but I can't seem to find more efficient float output. FFI to sprintf ? yuch.
Is your SMLNJ using lazy lists? :)
strictly speaking : no.
Try hmatrix or uvector.
uvector is _probably_ the long term answer even after I solve the double -> string problem. However, I would like to reiterate that it's the double -> string which is really the time/memory sink. I verified this by printing a simple string based on the value (to make sure the value was evaluated) and it runs fast enough for me. Is there an efficient way to output double -> binary ? I typically write my data files as binary anyway, because it's faster for graph and the like to handle them anyway. Brian
