WebSymbolic manipulations in MATLAB are carried out on symbolic variables, which can be either particular numbers or unspeciﬁed variables. The easiest way in which to deﬁne a variable as symbolic is with the syms command. Example 1. Suppose we would like to symbolically deﬁne the logistic model R(N) = aN(1− N K). WebTo create symbolic expressions, first create symbolic variables, and then use operations on them. For example, use syms x; x + 1 instead of sym ('x + 1'), exp (sym (pi)) instead of sym ('exp (pi)'), and syms f (var1,...,varN) instead of f (var1,...,varN) = sym ('f (var1,...,varN)'). Syntax x = sym ('x') A = sym ('a', [n1 ... nM]) A = sym ('a',n)
