A Special Condition In Vector Space# This question has a special form in Vector Space and in Matrix, We could write asAx=0Ax=0and define the Four Fundamental Subspaces ofAA, we have a hypothesis thatAAism×nm×nmatrix, and defineRR=rref(A)rref(A)which comes from Gaussian elimination. ...
dual vector space里面的元素是vector space上的线性函数。设V是一个vector space，V^{*}是其dual vector space，对于a \in V^{*},a ：V \to \mathbb{R}是一个V上的线性函数。如果V是有限维的，那么V^{**}\simeq V,即对偶的对偶就是自身。假设e_1,e_2,...,e_n是V的一组基，那么我们可以得到...

When solving linear equation solution or eigenvalue solution of large matrices, computer memory limitation requires the problem to be solved in a smaller linear space than the original linear space empowered by A. The smaller linear space has to be generated with the third kind or fourth kind ...
