Function Documentation

template<typename T , typename T2 >

bool almostEqual	(	const Eigen::MatrixBase< T > &	a,
		const Eigen::MatrixBase< T > &	b,
		T2	tol
	)

Are two eigen matrices almost equal?

                         {
  long x = T::RowsAtCompileTime;
  long y = T::ColsAtCompileTime;

  if (T::RowsAtCompileTime == Eigen::Dynamic ||
      T::ColsAtCompileTime == Eigen::Dynamic) {
    assert(a.rows() == b.rows());
    assert(a.cols() == b.cols());
    x = a.rows();
    y = a.cols();
  }

  for (long i = 0; i < x; i++) {
    for (long j = 0; j < y; j++) {
      T2 error = std::abs(a(i, j) - b(i, j));
      if (error >= tol) return false;
    }
  }
  return true;
