% RAND_RANGE Generates a value from the uniform distribution on the interval (xmin, xmax).
%
% INPUT:
%   * xmin,             Minimum possible value                                  scalar      []
%   * xmax,             Maximum possible value                                  scalar      []
%
% OUTPUT:
%   * x,                Pseudo-random number in (xmin, xmax)                    scalar      []
