C++ (Cpp) isRowMajor Examples

Example #1

bool multiArrayMessageMapToMatrixEigen(MultiArrayMessageType_& m, EigenType_& e)
{
  if (e.IsRowMajor != isRowMajor(m)) {
    ROS_ERROR("multiArrayMessageToMatrixEigen() failed because the storage order is not compatible.");
    return false;
  }

  e.resize(getRows(m), getCols(m));
  e = Eigen::Map<EigenType_>(m.data.data(), getRows(m), getCols(m));
  return true;
}

Example #2

bool multiArrayMessageCopyToMatrixEigen(const MultiArrayMessageType_& m, EigenType_& e)
{
  if (e.IsRowMajor != isRowMajor(m)) {
    ROS_ERROR("multiArrayMessageToMatrixEigen() failed because the storage order is not compatible.");
    return false;
  }

  EigenType_ tempE(getRows(m), getCols(m));
  tempE = Eigen::Map<const EigenType_>(m.data.data(), getRows(m), getCols(m));
  e = tempE;
  return true;
}
