function xdot = affine(t,x,flag,A,b)

% Compute the state derivative for the affine dynamic "dx/dt = A*x + b"
%
% Syntax:
%   "xdot = affine(t,x,flag,A,b)"
%
% Description:
%   Return the state derivative for the affine dynamics for the current
%   state vector "x" and time "t". See MATLAB help on "odefile" for more
%   detail.

xdot = A*x + b;
