SVD在数学上有多种应用,包括计算伪逆(pseudoinverse)、矩阵近似(matrix approximation)以及确定矩阵的秩(rank 线性无关向量的最大个数)、值域(range)和零空间(null space)。此外,SVD在科学、工程和统计学的各个领域都很有用,比如信号处理(signal processing)、数据最小二乘拟...

Here's how to calculate the singular value decomposition of a m×nm×n matrix AA by hand. We will see that SVD is closely related to the eigenvalues and eigenvectors of AA. As we remember, we can easily find the eigenvalues and eigenvectors for square matrices, yet AA can be rectangular...
