(eng): An algorithm is described for extracting a polynomial matrix factor featuring any subset of the zeros of a given non-singular polynomial matrix. It is assumed that the zeros to be extracted are given as input data. Complex or repeated zeros are allowed. The algorithm is based on interpolation and relies upon numerically reliable subroutines only. It uses a procedure that computes the generalized characteristic vectors of a polynomial matrix at a given point. It is programmed in the Polynomial Toolbox.
