ad_interfaceEM

Transforms two numbers (variances of independent directions) and an angle to an ellipsoid matrix.

ad_interfaceEM(Data, Mu, Sigma, Lambda, Nmodes = 1, Addmodes = 1, Nit = 1,
Verbose = 0)

`Data`	[1:n, 1:2] Numeric matrix with n observations and 2 feature dimensions.
`Mu`	List of l two-dimensional numeric vectors carrying mean vector.
`Sigma`	List of l 2x2 numeric matrices carrying covariance matrices.
`Lambda`	[1:l] Numeric vector with l weights for l Gaussian Mixture Model components.
`Nmodes`	Number of modes to initialize if no (Mu, Sigma, Lambda) is given.
`Nit`	Numerical value: max number of iterations.
`Addmodes`	Optional: Addmodes = 1: Allow EM to add modes. Addmodes = 0: do not allow EM to add modes.
`Verbose`	Optional: 0, 1 or 2. 0 = no output, 1 = messages, 2 = messages + plot. Default ==0. Print some outputs.

`Mu`	List of l two-dimensional numeric vectors carrying mean vector.
`Sigma`	List of l 2x2 numeric matrices carrying covariance matrices.
`Lambda`	[1:l] Numeric vector with l weights for l Gaussian Mixture Model components.
`MainAxesAngle`	List of length l with numeric vectors [1:3] with main axes and the angle between the first dimension of a 2D cartesian coordinate system the first main ax for all Gaussian Mixture Model components.
