Mathematics and Code EquivalentsMathematics and Code EquivalentsThe transition from mathematics to code or vice versa can be made with the aidof a few rules. They are listed here for future reference.To change from mathematics notation to MATLAB® notation, the user needsto:• Change superscripts to cell array indices.For example, p 1 → p{ 1}• Change subscripts to parentheses indices.1For example, p 2 → p( 2), and p 2 → p{ 1} ( 2)• Change parentheses indices to a second cell array index.For example, p 1 ( k – 1) → p{ 1,k – 1}• Change mathematics operators to MATLAB operators and toolbox functions.For example, ab → a*bThe following equations illustrate the notation used in figures.n = w 11 , p + 1 w 1, 2 p + 2 ... + w 1, R p + R bw 1, 1 w 1, 2 … w 1,RW =w 2, 1 w 2, 2 … w 2,Rw S, 1 w S, 2 … w S,Rxi
