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. More...

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

void	mlpack::math::Orthogonalize (arma::mat &x)
	Orthogonalize x in-place. More...

void	mlpack::math::RandVector (arma::vec &v)
	Overwrites a dimension-N vector to a random vector on the unit sphere in R^N. More...

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. More...

void	mlpack::math::Smat (const arma::vec &input, arma::mat &output)
	The inverse of Svec. More...

void	mlpack::math::Svec (const arma::mat &input, arma::vec &output)
	Upper triangular representation of a symmetric matrix, scaled such that, dot(Svec(A), Svec(B)) == dot(A, B) for symmetric A, B. More...

void	mlpack::math::Svec (const arma::sp_mat &input, arma::sp_vec &output)

size_t	mlpack::math::SvecIndex (size_t i, size_t j, size_t n)
	Return the index such that A[i,j] == factr(i, j) * svec(A)[pos(i, j)], where factr(i, j) = sqrt(2) if i != j and 1 otherwise. More...

void	mlpack::math::SymKronId (const arma::mat &A, arma::mat &op)
	If A is a symmetric matrix, then SymKronId returns an operator Op such that. More...

void	mlpack::math::VectorPower (arma::vec &vec, const double power)
	Auxiliary function to raise vector elements to a specific power. More...

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

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. More...
