SYNOPSIS

Namespaces

mlpack

Linear algebra utility functions, generally performed on matrices or vectors. mlpack::math

Miscellaneous math routines.

Functions

void mlpack::math::Center (const arma::mat &x, arma::mat &xCentered)

Creates a centered matrix, where centering is done by subtracting the sum over the columns (a column vector) from each column of the matrix. void mlpack::math::Orthogonalize (const arma::mat &x, arma::mat &W)

Orthogonalize x and return the result in W, using eigendecomposition. void mlpack::math::Orthogonalize (arma::mat &x)

Orthogonalize x in-place. void mlpack::math::RandVector (arma::vec &v)

Overwrites a dimension-N vector to a random vector on the unit sphere in R^N. void mlpack::math::RemoveRows (const arma::mat &input, const std::vector< size_t > &rowsToRemove, arma::mat &output)

Remove a certain set of rows in a matrix while copying to a second matrix. void mlpack::math::VectorPower (arma::vec &vec, const double power)

Auxiliary function to raise vector elements to a specific power. void mlpack::math::WhitenUsingEig (const arma::mat &x, arma::mat &xWhitened, arma::mat &whiteningMatrix)

Whitens a matrix using the eigendecomposition of the covariance matrix. void mlpack::math::WhitenUsingSVD (const arma::mat &x, arma::mat &xWhitened, arma::mat &whiteningMatrix)

Whitens a matrix using the singular value decomposition of the covariance matrix.
