Class DefaultFactory<N extends Number>

java.lang.Object
  org.ojalgo.matrix.factory.DefaultFactory<N>

All Implemented Interfaces:

MatrixFactory

Direct Known Subclasses:

JamaFactory

public class DefaultFactory<N extends Number>
extends Object
implements MatrixFactory

DefaultFactory creates instances of classes that implement the BasicMatrix interface and have constructors matching the MatrixFactory make(...) methods.

DefaultFactory uses reflection to call the appropriate 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.
