Abstract

The conjugate gradient method is developed for the solution of an arbitary operator equation. The fundamental differences between the conjugate gradient method and the conventional matrix methods, denoted by the generic name "method of moments" are also outlined. One of the major advantages of the conjugate gradient method is that a clearcut exposition on the nature of convergence can be defined. Numerical results are presented to illustrate the efficiency of this method and the FFT for certain special classes of problems.
