Abstract

Quadratic approximation is a three-dimensional analogue of the two-dimensional Padé approximation. The advantages of employing quadratic approximation are demonstrated by several examples. With automatic computers having a relatively inexpensive square root instruction, quadratic approximation is an attractive alternative to Padé approximation if convergence of the Padé approximation is not rapid.
