dem2ddat

Purpose

Generates two dimensional data for demos.

Synopsis 

data = dem2ddat(ndata)
[data, c] = dem2ddat(ndata)

Description

The data is drawn from three spherical Gaussian distributions with priors 0.3, 0.5 and 0.2; centres (2, 3.5), (0, 0) and (0,2); and standard deviations 0.2, 0.5 and 1.0. data = dem2ddat(ndata) generates ndata points.

[data, c] = dem2ddat(ndata) also returns a matrix containing the centres of the Gaussian distributions.
