hi!

i'm dealing with matrices here and want to plot its value into postscript. in fact, i just need a black spot where a matrix entry is not zero, white everywhere else. easy, isn't it?

particulary, my matrices have very few non-zero entries, so the ps file would only have a few black spots here and there.

now, what's the best way to write this in postscript? the first thing i tried was the image environment: works well as soon as you got used to the syntax, but the big disadvantage for me was that i have to explicitly code all the white pixels, so the eps file gets a lot bigger than needed (it feels).

the second thing i tried was defining a small "draw tiny box" command, then "move to" the non-zero spots, and evoke the function.
that's better then the image way (the files are a lot smaller), but it still feels like a hack somehow.

do you have any hints or suggestions for the issue? are there any commands or environment that would be better suited?

all hints appreciated!

cheers,
nico
