%'rotate_points': associated with GUI rotate_points.fig to introduce (2D) rotation parameters
%------------------------------------------------------------------------
% function T=rotate_points(Tinput)
% OUTPUT:
% T=vector size(1,3)
%     T(1): rotation angle
%     T(2): x coordiante of rotation axis
%     T(3): y coordiante of rotation axis
%
%INPUT:
% Tinput: like T, used to prefil the GUI edit boxs
