APPARATUS FOR PERFORMING A LINEAR INTERPOLATION ALGORITHM

摘要

A linear interpolation and numerical integration system employing U, X and Y arrays for computing additional sets of X and Y points in an X-Y coordinate system from a number of known sets of X and Y points. The U array is used to access 1P, DELTA P and 2P values which constitute assigned points along the X axis and reference the known X points. Computation of the additional Y points is done in accordance with the expression:Yi = XK + F(XK+1 - XK) where F is a fractional portion of the 1P value, which fractional portion is increased by DELTA P each computation of Yi. The necessary indexing and updating of the X and U array addresses and the P values is accomplished in an indexing section which operates time independently of the arithmetic means, thus permitting simultaneous computation and indexing functions in different Yi determinations.
