action_to_acceleration.m

The MDP toolbox proposes functions related to the resolution of discrete-time Markov Decision Proces

function [ax,ay]=action_to_acceleration(a)

%     action_to_acceleration: given an action a, this function computes the
%                             corresponding (ax,ay) vector
% Arguments --------------------------------------------------------------
%     a = the action taken (in 1:9) 
% Evaluation --------------------------------------------------------------
%     (ax,ay) = the corresponding acceleration vector's components.
%--------------------------------------------------------------------------
% In verbose mode, there is no difference to silent mode.
