Interface LUDecomposition

All Superinterfaces:

java.lang.AutoCloseable

public interface LUDecomposition
extends java.lang.AutoCloseable

LU decomposition utility class. As some decomposition implementation may allocate resources that need to be released a try-with-resource block has to be used to ensure correct resource management.

 try (LUDecomposition decomposition = m.decomposeLU()) {
     decomposition.solve(...)
 }
