Matlab function to compute intersection of two Gaussians (analytic solution)

[Ramón Casero Cañas]

Hi all,

I have added a function that computes the two intersection points of two Gaussian functions. This can be useful when working with a Gaussian Mixture Model

http://code.google.com/p/gerardus/source/browse/trunk/matlab/PointsToolbox/intersect_gaussians.m?r=974

The solution is analytical, not a numeric approximation. I computed the solution using Mathematica. The result can be seen in this image file:

Cheers,

Ramon.
