The Singular Value Decomposition (SVD) Calculator is a handy tool for performing matrix decomposition using the Singular Value Decomposition method. This mathematical technique plays a crucial role in various fields such as data analysis, image processing, and machine learning.
Formula: Singular Value Decomposition involves breaking down a matrix A into three simpler matrices: U, Σ, and V^T. The formula can be expressed as A = UΣV^T, where U and V^T are orthogonal matrices, and Σ is a diagonal matrix with singular values.
How to Use:
- Enter the matrix values in the input field, separating them with commas.
- Click the “Calculate” button to perform the SVD.
- The result will be displayed in the designated field.
Example: Suppose you have the matrix A = [1, 2; 3, 4]. Enter “1,2,3,4” in the input field, click “Calculate,” and the SVD result will be presented.
