I'm trying to create an STL vector (std::vector) containing variable-length, double-precision Eigen vectors (Eigen::VectorXd). The following code generates a compiler error "Invalid template arguments".

Code: Select all

#include <vector>
#include <Eigen/Core>
int main(int argc, const char* argv[]) {
  vector<Eigen::VectorXd> vec;
}


I understand that there's an issue with constant-sized Eigen matrices/vectors (e.g., Eigen::Vector4f) and the STL classes, but the manual seems to imply that variable-sized matrices/vectors are OK. Am I missing something?

Thanks in advance for the help! (I'm sorry if this is a dumb question, or if it's come up before; I did a few searches on this forum, but nothing relevant came up.)

EDIT: Never mind! Problem solved! User error.
