SVF (Matrix)
- is any set of values.
Description
- This function shows the Singular value of a given matrix in descending order.
- In , is any matrix with array of values.
- Singular value decomposition is defined by the factorization of a real or complex matrix.
- It is the generalization of the Eigen decomposition of a symmetric matrix with positive eigen values to any mxn matrix through an extension of the polar decomposition.
- Singular value decomposition is of the form where is any square real or complex Unitary matrix of order .
- is a mxn rectangular diagonal matrix with non negative real numbers.
- V is also any square real or complex Unitary matrix of order nxn.
- The columns of U and V are called left Singular and right Singular vectors of the matrix.
- To find Singular Value Decomposition we have to follow the below rules:
*The left-singular vectors of the matrix M are a set of orthonormal eigenvectors of MM∗. *The right-singular vectors of M are a set of orthonormal eigenvectors of Failed to parse (syntax error): {\displaystyle M^{∗}M} . *The non-zero singular values of M (found on the diagonal entries of Σ) are the square roots of the non-zero eigenvalues of both Failed to parse (syntax error): {\displaystyle M^∗M} and Failed to parse (syntax error): {\displaystyle MM^∗} .
