Detailed Description

Class for 3d matrices with up to 4 rows and 4 columns. Actual size may be smaller but not bigger than this size. The memory allocation is static in the class members, so no heap space is used.

double UMatrix4::density	(	UMatrix4	v,

	)

Find density value for a vector position 'v', when this matrix is assumed to be a covariance matrix.
The mean is in vector vm.

double UMatrix4::densityQi	(	UMatrix4	vd,
		double	det,
		bool *	isOK = `NULL`
	)

Find density function at point 'v', for a distribution with 'this' as inverse covariance matrix and determinant of covariance matrix of 'det'. Mean value of distribution is assumed to be zero.
On return is 'isOK' false if function failed.

UMatrix4 UMatrix4::eig2x2	(	bool *	complex,

	)

Find eigenvalues and eigenvectors for 2x2 matrix. If matrix A is larger than 2x2, then solution is found for the 2x2 formed by the first 2 rows and columns. If roots are complex, the 'complex' flag is set true and the returned eigenvalues and vectors are the real part only. The eigenvalues are returned in a vector (size 2) and the eigenvectors are returned in 'eigenvectors' as columns corresponding to the elements in this vector of eigenvalues.
