Performs singular value decomposition to compute the four fundamental subspaces of a matrix, namely the right and left null spaces and the right and left image spaces.
Name | Description |
---|---|
a | Specifies an m-by-n matrix. |
0 | Directs LabVIEW to perform the decomposition in a reduced-size format. |

sv | Returns the singular values of a. sv is a real vector with min(m, n) elements. |
u | Returns an m-by-min(m, n) unitary matrix. |
s | Returns a square matrix of order min(m, n) with the singular values on the main diagonal and zeros elsewhere. |
v | Returns an n-by-min(m, n) unitary matrix. |
Singular value decomposition is a computationally expensive but powerful algorithm for solving a number of problems, including finding least square solutions, finding the 2-norm and 2-norm condition estimate, and determining the rank of a matrix. svd computes unitary matrices u and v such that the input matrix is equivalent to u*s*conjugate(v').
