Detailed Description

template<class Matrix_, class EigenVector_>
class irlba::Centered< Matrix_, EigenVector_ >

Wrapper for a centered matrix.

Template Parameters

Matrix_	Class satisfying the MockMatrix interface, or a floating-point Eigen::Matrix.
EigenVector_	A floating-point Eigen::Vector class for the column centers and matrix-vector product.

This class computes the matrix-vector product after centering all columns in Matrix_, i.e., subtracting the mean of each column from the values of that column. Naively doing such an operation would involve loss of sparsity, which we avoid by deferring the subtraction into the subspace defined by rhs.

This class satisfies the MockMatrix interface and implements all of its methods/typedefs.

Parameters
