MATLAB的svd()函数是一个强大的工具,用于对矩阵进行奇异值分解。这个函数将一个矩阵分解成三个矩阵的乘积,其中一个是对角的,包含原始矩阵的奇异值。svd()函数经常在图像处理、信号处理和机器学习等各种应用中使用。 One of the key advantages of using the svd() function in MATLAB is its ability to handle ...
奇异值分解 (sigular value decomposition,SVD) 是一种正交矩阵分解法；SVD是最可靠的分解法，但是它比QR 分解（QR分解法是将矩阵分解成一个正规正交矩阵与上三角形矩阵。）法要花上近十倍的计算时间。[U,S,V]=svd(A)，其中U和V代表二个相互正交矩阵，而S代表一对角矩阵。 和QR分解法相同者， ...
The svd function cannot find the exact singular values in terms of symbolic numbers. Instead, it returns them in terms of the root function. Use vpa to numerically approximate the singular values. Get sigmaVpa = vpa(sigma) sigmaVpa = ⎛⎜⎜⎜⎜⎜⎝91.90338229938887559838064521710541...

For complete decompositions, svd(A) returns V as an n-by-n unitary matrix satisfying VVH=VHV=In. The columns of V that do not correspond to nonzero singular values form a set of orthonormal basis vectors for the null space of A. Different machines and releases of MATLAB can produce diff...
