Class AbsMatrixNxNTest

java.lang.Object
org.djunits.vecmat.dn.AbsMatrixNxNTest
public class AbsMatrixNxNTest extends Object
Tests for AbsMatrixNxN.

This class provides exhaustive coverage of AbsMatrixNxN and all inherited functionality from AbsSquareMatrix, AbsMatrix, AbsTable, AbsVectorMatrix and Value. The tests intentionally use an NxN matrix with N = 2 to exercise the generic NxN implementation paths while keeping test logic manageable.
