# Package org.ejml.alg.dense.decomposition.qr

Class Summary Class Description QRColPivDecompositionHouseholderColumn Performs QR decomposition with column pivoting.QRDecompositionBlock64 Wrapper that allows`QRDecomposition`

(BlockMatrix64F) to be used as a`QRDecomposition`

(DenseMatrix64F).QRDecompositionHouseholder This variation of QR decomposition uses reflections to compute the Q matrix.QRDecompositionHouseholderColumn Householder QR decomposition is rich in operations along the columns of the matrix.QRDecompositionHouseholderTran Householder QR decomposition is rich in operations along the columns of the matrix.QrHelperFunctions Contains different functions that are useful for computing the QR decomposition of a matrix.QrUpdate The effects of adding and removing rows from the A matrix in a QR decomposition can be computed much faster than simply recomputing the whole decomposition.
