of the solution of a matrix eigenvalue problem, but understand how to deduce, in order to understand the meaning of the deeper. This content requires the reader to have some basic linear algebra basis, such as eigenvalue, eigenvector concept, space projection, point multiplication and other basic knowledge. In addition to the other formulas, I try to speak more simple and clear.Lda:The full name of LDA is linear discriminant analysis (linear discrimi
