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...

Null space basis vectors, returned in the columns of a matrix.Zsatisfies the properties: A*Zhas negligible elements. size(Z,2)is an estimate of the nullity ofA. Ifrank(A)(orrank(A,tol)) is equal tosize(A,2), thenZis empty.
THE RANGE AND THE NULL SPACE OF A MATRIX Suppose that A is an m×n matrix with real entries.There are two important subspaces associated to the matrix A.One is a subspace of R m.The other is a subspace of R n.We will assume throughout that all vectors have real entries.THE RANGE ...
