Constructor & Destructor Documentation

SVD()

pcl::SVD::SVD ( const matrix &  A )

inline

Singular Value Decomposition: A = U*W*Vt

The dimensions of A are n rows and m columns. U is an n x m matrix. The m components of W are the positive diagonal elements of W, and each column of V (m x m) is the eigenvector for the corresponding element of W.

On output, this constructor stores U, W and V in the corresponding members of this object.
