Nullspace，指的是由“零元素”构成的空间，通常指某个“向量空间”的“零子空间”。例如，在由全部两行三列实矩阵组成的“向量空间”里，nullspace就是一个元素构成的子空间，具体形式如：┌ 0 0 0┐ └0 0 0┘ 值得注意的是，nullspace与特征向量的概念并无直接关联。在矩阵理论中，特征向量是...

The nullspace stays the same: \bm{N(A)=N(U)=N(R)} . The nullspace becomes easiest to see when we reach the reduced row echelon form \bm{R}=rref(\bm{A}) . The pivot columns of \bm{R} contain \bm{I} . It can be found that each pivot column contains only a one-value en...
幂零矩阵的一个充要条件 一个学弟曾经告诉我,关于复数域上幂零矩阵 A 的一个充要条件: A = AB-BA, \quad \exists B \in M_n(\mathbb{C}) \\特此记录。 证明分几个小步骤: 必要性对若当块成立,若A为(上三角)若… cuzperf打开知乎App 在「我的页」右上角打开扫一扫 其他扫码方式:微信 下载知乎...
In this article we consider a class of functions, called D-polynomials, which are contained in the null space of certain second order differential operators with constant coefficients. The class of splines generated by these D-polynomials strictly contains the polynomial, trigonometric, and hyperbolic...
In the space I r of the invariant r-dimensional subspaces of a null system in (2r +1)-dimensional projective space, W.L. Chow characterized the basic group of transformations of I r as all the transformations φ: I r → I r which are bijective and such that φ and φ 1 preserve ...
