线性代数 rank-nullity theorem 是什么意思 解释一下它阐述了什么basis是什么alternate basis是什么
ank-nullity theorem。齐次线性方程组的解空间的维数与系数矩阵的秩的关系定理。
rank(A) + nullity(A) = dim(R^n), 其中A是m*n矩阵。
basis 向量空间的基。
A是p*n矩阵(p行n列)，A的秩rank(A)=n，证明rank(A’A)=n (A’表示A的转置)
证明：因为行秩=列秩，所以rank(A^(T))=n。
由rank-nullity theorem知：A的零度为0，A^(T)的零度也为0。
考虑A^(T)A的零度，即考虑A^(T)Ax=0。
扩展资料：
对一个 n 行 n 列的非零矩阵 A，如果存在一个矩阵 B 使 AB = BA =E（E是单位矩阵），则 A 为非奇异矩阵（或称可逆矩阵），B为A的逆阵。
矩阵非奇异（可逆）当且仅当它的行列式不为零。矩阵非奇异当且仅当它代表的线性变换是个自同构。
矩阵半正定当且仅当它的每个特征值大于或等于零。矩阵正定当且仅当它的每个特征值都大于零。解线性方程组的克拉默法则。判断线性方程组有无非零实根的增广矩阵和系数矩阵的关系。
