iris with matlab.irisData is 150x5. row: Sepal.Length Sepal.Width Petal.Length Petal.Width Group(1,2,or 3) the first 50x5 is Isis-setosa(1), the second 50x5 is Isis-versicolor(2), the last 50x5 is Isis-virginica(3). !!! Caution !!! X(50 + 21, :) equals X(50 + 50 + 27, :), but Y(50 + 50 + 21) DOESNOT equal Y(50 + 50 + 27)! So the algorithm will NEVER be 100 correct.

说明：  初始对准是捷联惯导系统进行导航的前提，初始对准的好坏将直接影响到系统的导航精度。捷联惯导系统(SINS)初始对准的本质是确定载体的初始姿态。(The initial alignment of strapdown inertial navigation system is the premise for navigation, initial alignment will directly affect the quality of the navigation system precision. Strapdown inertial navigation system (SINS) is to determine the nature of the initial alignment of the initial attitude of the vehicle.)
