CVT_1D_NONUNIFORM is a MATLAB program which allows the user to watch the evolution of an approximate CVT for a nonuniform density function.
The number of generator points defaults to 10, and is stored in an internal variable N.
The points are initialized randomly, or may be set uniformly, or even all set to zero. This is controlled by an internal parameter SAMPLE_FUNCTION_INIT.
The density function d(s) is specified by the value of DENSITY_FUNCTION:
The variable SAMPLE_NUM_CVT controls the number of sample points generated on each CVT iteration. It should be 20 to 100 times greater than the value of N.
The variable SAMPLE_NUM_STEPS controls the number of CVT iterations taken. A value of 100 is probably enough.
