Author's summary: Spaces of piecewise polynomials defined over triangulations of the plane play an important role in data fitting, in the solution of boundary-value problems for partial differential equations, and in computer-aided design. Such spaces seem to have been used less for data fitting than they deserve to be, perhaps because they are often considered to be too complicated to deal with numerically. The purpose of this paper is to help dispel this misconception by presenting a series of simple algorithms for dealing with such spaces on a digital computer.
