pca
说明: 在MATLAB上所使用的PCA程序,主要應用於過濾相對較不重要的特徵值(dimension),例如在三度空間的某些點具有(x,y,z)值,因為這些點有共同的一個持徵,就是z值相對於x,y值來得小很多(不明顯),所以就以X,Y軸來表示這些點。此時就達成去除掉z的特徵值(dimension)。
(MATLAB used in the PCA procedure, mainly used in filtering relatively unimportant eigenvalue (dimension), for example, in some points with three-dimensional (x, y, z) values, because these points have a common one sign holders, that is, z values compared with the x, y values much smaller than (not obvious), so on to X, Y axis to express these points. Reached at this time to get rid of z eigenvalues (dimension).)
