function r = expand(s)
%EXPAND Symbolic expansion.
%   EXPAND(S) writes each element of a symbolic expression S as a
%   product of its factors.  EXPAND is most often used on polynomials,
%   but also expands trigonometric, exponential and logarithmic functions.
%
%   Examples:
%      expand((x+1)^3)   returns  x^3+3*x^2+3*x+1
%      expand(sin(x+y))  returns  sin(x)*cos(y)+cos(x)*sin(y)
%      expand(exp(x+y))  returns  exp(x)*exp(y)
