Hi,
Imagine this:
x = [1,2,3,4;5,6,7,8]
y = [-0.1,0,7,4;-1,-1,2,7]
y(1,1) = -0.1
as it's negative, I have to plot x(1,1) in one color.
y(1,3) = 7 is positive then I plot x(1,3) in other color.
What I've also tried to do is to divide the plotting window with a line
(above it are the positive values, and under the negative ones) and
give different a background color to each part, but I think that is a
question more for the gnuplot mailling list :)
thanks!
Alvaro.
How about
>> find(ismember(X,Y))
ans =
