A linear difference equation is also called a linear recurrence relation, because it can be used to compute recursively each y k from the preceding y-values. More specifically, if y 0 is specified, then there is a unique sequence {y k} that satisfies the equation, for we can calculate, for k = 0, 1, 2, and so on, y 1 = z 0 - a y 0, y 2 = z 1 ...
