A discrete-time orthogonal spline collocation scheme is formulated and analyzed for a problem governing the transverse vibrations of a clamped square plate. The problem is reformulated as a Schrรถdinger-type system which is then approximated by a Crank-Nicolson orthogonal spline collocation scheme. T

## Abstract This paper is concerned with the numerical solution of a symmetric indefinite system which is a generalization of the Karushโ€“Kuhnโ€“Tucker system. Following the recent approach of Lukลกan and Vlฤek, we propose to solve this system by a preconditioned conjugate gradient (PCG) algorithm and
