cvt_square_nonuniform, a MATLAB code which iteratively calculates a Centroidal Voronoi Tessellation (CVT) in a square with a nonuniform density.
CVT_SQUARE_NONUNIFORM works in the square [-1,+1]x[-1,+1] with density rho(x,y)=sqrt(x^4+y^4). The function starts from a random configuration of generators. It repeatedly uses uniform sampling to estimate the centers of mass of the Voronoi subregions, and then replaces the generators by the centers of mass.
The calling sequence is:
p = cvt_square_nonuniform ( n, sample_num )
