Generation of a 2D classification problem: Gaussian circle and blob

    A = GENDATG(N,S1,S2)

 N Dataset size, or 2-element array of class sizes (default: [50 50]).
 S1 Standard deviation of the circle, default 0.1
 S2 Standard deviation of the blob, default 0.3.

 A Dataset.


Generation of a two-class problem. The first class is a set of uniformly  distributed points on the unit circle with a normally distributed  Gaussian radial deviation. The second class is a Gaussian distributed  2D spherical dataset in the origin with standard deviation S2.
