Sylvester Matrix
S = SYLVESTER(P,Q) returns the Sylvester matrix S that is associated with the two polynomial representations P and Q, of degree Dp and Dq, respectively. S is a (Dp+Dq)-by-(Dp+Dq) square matrix. Note that the degree of the polynomial is one less the the number of elements of its representation: degree(P) = numel(P)-1.
SYLVESTER(P,Q, [Mp Mq]) returns a generalization by specifiying the size. The Sylvester matrix S will be a, in general non-square, (Mp+Mq)-by-K matrix, with K being the maximum of (Mp+Dp) and (Mq+Dq).
Examples:
P = [1 2 3 4] ; Q = [6 7] ; % Dp = 3, Dq = 1 ;
M = sylvester(P,Q)
% 1 2 3 4
% 6 7 0 0
% 0 6 7 0
% 0 0 6 7
M = sylvester([1 0 3],[2 4],[3 1])
% -> a non-square sylvester matrix
% 1 0 3 0 0
% 0 1 0 3 0
% 0 0 1 0 3
% 2 4 0 0 0
