Plot_GM

Generate ellipse and landscape plots of Gaussian mixture.

Description

A reviewer of my EM_GM code suggests that it would be nice to separate the Gaussian mixture (GM) plot function from the code, so that it can be used alone.

The Plot_GM function includes input verifications, 1D and 2D plots of GM. For 2D, it can be controlled to plot ellipses and/or landscapes of GM. It has detail descrptions of the inputs.

Please contact me if you find any bug.

Works great!
I wanted to display the ellipses superimposed on a 2D image, so just modifed the code a bit to pass a figure handle as input parameter. Also, having the color of the ellipse as an optional input parameter will be useful.

I use your code in Bayes Classifier.
With my data, the Log Likelihood is NaN and Covariance matrix is singular --> det(Cov) = 0
So I can't process futher.
Please show me how to deal this problem
Thank you
