N. Saxena et Jj. Clark, ANALOG SYSTEM FOR EIGENVALUE COMPUTATION AND SORTING BASED ON AN ISOSPECTRAL MATRIX FLOW, Electronics Letters, 31(1), 1995, pp. 24-26
An analogue system for the computation of the eigenvalues of symmetric
matrices and for sorting lists is described. The computation is based
on an isospectral matrix flow. A fully parallel continuous time imple
mentation of the equations is presented. The implementation was simula
ted using PSPICE, and the results of the simulation are described.
