Interface MatrixDecomposition.EconomySize<N extends Number>

All Superinterfaces:

MatrixDecomposition<N>, Structure1D, Structure2D

All Known Subinterfaces:

Bidiagonal<N>, QR<N>, SingularValue<N>

Enclosing interface:

MatrixDecomposition<N extends Number>

public static interface MatrixDecomposition.EconomySize<N extends Number>
extends MatrixDecomposition<N>

Several matrix decompositions can be expressed "economy sized" - some rows or columns of the decomposed matrix parts are not needed for the most releveant use cases, and can therefore be left out. By default these matrix decompositions should be "economy sized". Setting #setFullSize(boolean) to true should switch to "full sized".
