# 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.
