试题来源: 解析 nullspace,就是由“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就是由┏ 0 0 0┓┗0 0 0┛一个元素构成的子空间.nullspace与特征向量没有关系.反馈 收藏
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...
Create a 3-by-3 matrix of ones. This matrix is rank deficient, with two of the singular values being equal to zero. A = ones(3) A =3×31 1 1 1 1 1 1 1 1 Calculate an orthonormal basis for the null space ofA. Confirm thatAx1=0, within round-off error. ...
The null space of a matrix A is the set of all solutions to the equation Ax=0. The null space is a vector subspace of R^n, where n is the number of columns of A. Why is the null space of a matrix important? If the null space of A contains only the zero vector, then Ax=b...

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 ...
Syntax Z = null(A)Description Z = null(A) returns a list of vectors that form the basis for the null space of a matrix A. The product A*Z is zero. size(Z, 2) is the nullity of A. If A has full rank, Z is empty. example...
