gaussian_2d


gaussian_2d, a MATLAB code which evaluates a general Gaussian function of a 2D argument.

A formula for the Gaussian function at the point (x,y) is:

      g(c,x,y,xmu,ymu,xsigma,ysigma,A) = c * exp ( 1/2 xy' * A * xy )
      
where xy is the vector
      [ ( x - xmu ) / sigma,
        ( y - ymu ) / sigma ]
      
and A is a positive definite symmetric matrix.
