Hi,
I have a fixed bivariate gaussian density function, and I want to
compute the coordinates (x(l), y(l)) of a given level curve, where l
is the parameter of the curve. I can easily plot the level x curve
with matplotlib, using function 'contour', but I have no idea about
how to get its coordinates (something like an (N,2) array specifying
the coordinates of N points along the curve). With fsolve I can find
one of such points, but its is not enough :)
For bivariate normal distributions, these equal-density contours
are ellipses which you can write down the parametric form
of (x,y) from the mean and covariance matrix of your bivariate normal distribution.
Thanks in advance for your help,
Best
