Invalid size when Initializing Vector4f

问题

当我尝试在ROS / PCL中运行此行时，我收到以下错误：

  1. Eigen::Vector4f normalized(3,1);

我得到以下错误信息：

  1. /usr/include/eigen3/Eigen/src/Core/PlainObjectBase.h:281: 
  2. void Eigen::PlainObjectBase<Derived>::resize(Eigen::Index, Eigen::Index) 
  3. [with Derived = Eigen::Matrix<float, 4, 1>; Eigen::Index = long int]: 
  4. Assertion 
  5. `(!(RowsAtCompileTime!=Dynamic) || (rows==RowsAtCompileTime)) && 
  6. (!(ColsAtCompileTime!=Dynamic) || (cols==ColsAtCompileTime)) && 
  7. (!(RowsAtCompileTime==Dynamic && MaxRowsAtCompileTime!=Dynamic) || 
  8. (rows<=MaxRowsAtCompileTime)) && (!(ColsAtCompileTime==Dynamic && 
  9. MaxColsAtCompileTime!=Dynamic) || (cols<=MaxColsAtCompileTime)) && rows>=0 && cols>=0 &&
  10.  "Invalid sizes when resizing a matrix or array."' failed.
  11. Aborted (core dumped)

我使用的是Ubuntu 20.04，Eigen 3.3.7。

请问我应该如何解决这个问题？提前感谢。

I get the following Error:

  11. Aborted (core dumped)

I'm using Ubuntu 20.04, Eigen 3.3.7.

Can you please tell me how can I solve that? thanks in advance.

@Homer512解释的解决方案是：

  1. normal.normalized();
