Class MatrixFactory<N extends Number>

java.lang.Object
  org.ojalgo.matrix.MatrixFactory<N>

All Implemented Interfaces:

BasicMatrix.Factory

public final class MatrixFactory<N extends Number>
extends Object
implements BasicMatrix.Factory

MatrixFactory creates instances of classes that implement the BasicMatrix interface and have a constructor that takes a MatrixStore as input.

MatrixFactory uses reflection to call the constructor. This takes slightly longer than calling the matrix' constructors directly. If you need to instantiate a large number of small matrices; using DefaultFactory may not be your best alternative. In that case you should consider coding a different MatrixFactory implementation. In the vast majority of cases you do not need to worry about this.
