The well-known connection between Pad6 approximants to Stieltjes functions and orthogonal polynomials is crucial in locating zeros and poles and in convergence theorems. In the present paper we extend similar types of analysis to more elaborate forms of approximation. It transpires that the link wit

Given a square matrix A, we discuss the problem of seeking some constrained matrix C which satisfies (i) A + C =M and (ii) AC=M where M is symmetric, or nearly so. ## Typical constraints on C include low rank, orthogonality and low-rank departures from a unit matrix. Graphical representation is d
