How do I plot something like this in Maxima? 13:43 plot3d([x-y+1,y,x], [x, -3, 3], [y, -3, 3]); 13:45 You can also use the original form of your expression... 13:59 Okay, then I have to ask a second question, I tried to print multiple planes in one window with this: 13:59 plot3d([[1,0,0]+x*[1,0,1]+y*[-1,1,0],[-1,1,1]+x*[-2,2,1]+y*[-1,-1,0]],[x,-3,3],[y,-3,3],[plot_format,openmath]); 13:59 List [[- y + x + 1, y, x], [- y - 2 x - 1, - y + 2 x + 1, x + 1]] 13:59 is not of length 3 13:59 -- an error. Quitting. To debug this try debugmode(true); 13:59 With one plane it's working, with two it's not. Why? 14:03 The syntax is either: 14:03 plot3d(z(x,y), x-range, y-range); 14:03 or: plot3d(3d-vector(x,y), x-range, y-range); 14:04 plot3d currently doesn't understand lists of expressions to plot. 14:04 Does that mean, it's not possible to plot more than one plane into one system? 14:05 Im not sure. Perhaps you can somehow tell it to use replot instead of plot ... 14:05 I don't know about it though. You could ask on the mailing list. 14:06 plot3d DOES understand expressions of list, just not vectors... plot3d([sin(x^2+y^2),cos(x^2+y^2)],...] is possible 14:07 I thought maybe I'm missen something, because I saw a post of some teacher complimenting Maxima for the ability of showing intersections of planes :S 14:08 Oh wait 14:08 it's not possible 14:08 sorry 14:08 Just read that in the manual, weird 14:08 okay thank you :) 14:08 -!- Surma(n=Surma_@c157221.adsl.hansenet.de) has left #maxima 14:09 Some people leave just to fast to answer them ... 14:10 The manual might be outdated...
