[Solved] What does the matrix S represent in the MATLAB command [U, S, V] = svd(A);? — Ans: A diagonal matrix containing the singular values of A | MATLAB

MATLAB - Linear Algebra

What does the matrix S represent in the MATLAB command [U, S, V] = svd(A);?

AA diagonal matrix containing the singular values of <code>A</code>

BThe inverse of matrix <code>A</code>

CThe transpose of matrix <code>A</code>

DA matrix of eigenvectors of <code>A</code>

Step-by-Step Solution

Solution:

Step 1: Understand the output of svd
The MATLAB function svd decomposes a matrix A into three matrices: U, S, and V.
Step 2: Identify the role of S
The matrix S is a diagonal matrix containing the singular values of A, which are always non-negative and sorted in descending order.
Final Answer:
A diagonal matrix containing the singular values of A -> Option A
Quick Check:
Matrix S = Singular values diagonal matrix [OK]

Quick Trick: Singular values are always on the diagonal of S [OK]
