| Abstract: | On the basis of iinear equations, the first two parts of the paper give the analytical expression of oblique projection and orthogonal projection of vector in subspace. Cousequently, the definitions of the matrix of oblique projection and the matrix of orthogonal projection hove been drawn; besides, the besic properties of them and the way to find a solution to the mataix of orthogonal projection have been discussed.In the third part, according to the equinalence relation between the matrix of orthogonal projection and the generalized inverse matrix which can content Penr-ose's 1st and 3rd article, and on the basis of the theory of linear ecuations, the general expression of soluing this generalized irnerse matrix has been given. |
