Implementation of class "polyMatrix" for storing a matrix of polynomials and implements
basic matrix operations; including a determinant and characteristic polynomial.
It is based on the package 'polynom' and uses a lot of its methods to implement matrix operations.
This package includes 3 methods of triangularization of polynomial matrices:
Extended Euclidean algorithm which is most classical but numerically unstable;
Sylvester algorithm based on LQ decomposition;
Interpolation algorithm is based on LQ decomposition and Newton interpolation.
Both methods are described in

Metabolomics Approach
Mengci Li, Shouli Wang, Guoxiang Xie, Tianlu Chen, Wei Jia
Poly-PK strategy is a new strategy of pharmacokinetic analysis of multi-component drugs (Guoxiang Xie, Tianlu Chen, Wei Jia, et al. (2012)<doi:10.1021/pr300318m>; Ke Lan, Guoxiang Xie and Wei Jia. (2013)<doi:10.1155/2013/819147>). This package is the first implementation of the Poly-PK strategy with 10 easy-to-use functions.
