The PeacemanRachford ADI technique is a well-known method for solving, say, large-scale sets of linear equations arising out of the numerical solution by difference methods of second-order elliptic and parabolic partial differential equations. The present paper demonstrates how the algorithm can be conveniently arranged for computational purposes, and analyses the problems concerning the use of serial-access auxiliary storage equipment.
