TABLE OF CONTENTS This chapter is an introduction to the Lookup Tables library. This is the sixth library in the Simulink group of libraries and contains the blocks shown below. Their functions are illustrated with examples. The terminology monotonically increasing [1] is used throughout this chapter, and it is defined in the footnote below.
[1] Monotonically increasing and monotonically decreasing sequences are sequences in which the successive values either consistently increase or decrease but do not oscillate in relative value. Each value of a monotonic increasing sequence is greater than, or equal to the preceding value; likewise, each value of a monotonic decreasing sequence is less than, or equal to the preceding value. Stated in other words, a monotonically increasing function is one resulting from a partially ordered domain to a partially ordered range such that x ? y implies that f(x) ? f(y). Likewise, a monotonically decreasing function is one resulting from a partially ordered domain to a partially ordered range such that x ? y implies that f(x) > f(y).
The Lookup Table block computes an approximation to a function y = f( x) where the data vectors x and y are given, and it is required that the x data vector must be monotonically increasing. Moreover, the length of the x and y data vectors must be the same. Please refer to the Help menu for...
