C++ (Cpp) Matrix33::Determinant Examples

Example #1

// Helpful print functions
void print_matrix(Matrix33 const &_matrix)
{
  DebugLogPrint("MATRIX:\n");
  for (int i = 0; i < 3; ++i)
  {
    DebugLogPrint("ROW%d:", i);
    for (int j = 0; j < 3; ++j)
    {
      DebugLogPrint(" %f ", _matrix.values[i][j]);
    }
    DebugLogPrint("\n");
  }
  DebugLogPrint("DETERMINANT: %f\n", _matrix.Determinant());
}

Example #2

float InertiaMatrix::Adjoint( int skip_r, int skip_c ) const {
	Matrix33 sub = Submatrix( skip_r, skip_c );
	return pow(-1.0f, float(skip_r + skip_c)) * sub.Determinant();
}
