Abstract
Continuing our previous analysis, we derive the exact number of conjugate g radient iterations needed (to achieve a given tolerance) for the one-dimens ional discrete Poisson equation on a uniform grid, and a particularly smoot h solution vector. Mathematics Subject Classification (1991): 65F10.
