using subplot i make for example 4 plots i would also put several computed vaklues 9mean, min, max,...etc) on the same page before plotting it on paper i could use the text command to position each line filled with numers and text however, this seesm to me a rather clumsy way of doing. does anyone know a solution t... 13 Aug 2010 10:17

suppose I have an equation x^2+x+y^2+3*y=5*y^2+3*y+3*x*y+5 and I want to find the set of (x,y) that satisfy the equation.
Question How can i do that? I've been trying, solve, explot and subs. I can get the graph, but i cannot get the (x,y) pairs that I want. When I use function solve to solve the equation in term of x or y and then substitute the numeric value for one of them to find the other, I got the problem about complex numer.... 12 Aug 2010 11:28

My question is whether it is possible to capture/catch every error that occurs somewhere (arbitrary) in the object methods, without using try/catch or some sort of error detector like: if x>y then call the error function? In other words, when an error occurs the error ... 12 Aug 2010 11:28

Changing colors of stacked bar graph
Hi. I'm trying to create a stacked bar graph but to change the colors of the bars from the default to something that's more legible for my needs. My problem is that I expect to have a bunch of zeros (so some bars won't show up) which means I need a more distinguishing color map. Here is what I have countErrorType is... 12 Aug 2010 18:04
