Class RawDecomposition

java.lang.Object

org.ojalgo.matrix.decomposition.AbstractDecomposition<Double, R064Store>

org.ojalgo.matrix.decomposition.RawDecomposition

All Implemented Interfaces:

MatrixDecomposition<Double>, Structure1D, Structure2D

Direct Known Subclasses:

RawCholesky, RawEigenvalue, RawLU, RawQR, RawSingularValue

abstract class RawDecomposition
extends AbstractDecomposition<Double, R064Store>

In many ways similar to InPlaceDecomposition but this class is hardwired to work with double[][] data. Most of it's originates from JAMA, but have been significantly refactored or even (re)written from scratch.
