15:12 <Beererde> hi. what does %r1, %r2, ... mean?
15:25 <lindi-> Beererde: where?
15:26 <Beererde> lindi-: as result of a solve() call: [[x = %r5, y = 0], [x = 0, y = %r6], ...
15:26 <lindi-> Beererde: a free variable i guess
15:26 <Beererde> lindi-: ah ok, so some real number?
15:26 <lindi-> yep
15:27 <Beererde> ok thanks  :)

16:48 <cunzhang> hi,use plot3d to plot 3d drawing,  how to set the 3-axis range?
16:50 <lindi-> doesn't seem to be supported :/
16:50 <lindi-> cunzhang: you could define your function so that it only has values within some range
16:51 <cunzhang> lindi-: how to define it?
16:51 <cunzhang> lindi-: gnuplot can do this ?
16:51 <cunzhang> http://www.walkingrandomly.com/?p=19
16:51 <cunzhang> lindi-: I hope to draw this picture 
16:52 <cunzhang> so funny

16:59 <lindi-> cunzhang: plot3d('(if (f(x,y) > 0.5) then 0.5 else f(x,y)),[x,1,4],[y,1,4]);
16:59 <lindi-> cunzhang: would plot anything over 0.5 as 0.5
16:59 <cunzhang> lindi-: thank you
16:59 <cunzhang> :)
17:04 <cunzhang> lindi-: get it!
17:04 <cunzhang> plot3d('(if (f(x,y) > 0.001) then 0.001 else if (f(x,y)<0) then 0 else f(x,y)),[x,-3,3],[y,-5,5])
17:04 <cunzhang> lindi-: try this command in maxima :)
17:04 <lindi-> with what f?
17:05 <cunzhang> sorry
17:05 <cunzhang> f(x,y):=exp(-x^2-y^2/2)*cos(4*x)+exp(-3*((x+0.5)^2+y^2/2))
17:05 <cunzhang> :)
17:05 <cunzhang> will plot "HI" :)
17:06 <cunzhang> but the effect is not good 
17:11 <cunzhang> lindi-: thank you for your help.
17:11 <cunzhang> I'm going to sleep ^_^  goodbye

17:40 <Beererde> how do i compose the moebius-transform so that h(0)=-1, h(1)=-i and h(oo)=1 ?
17:40 <Beererde> sorry, wrong channel
