你好 想请问有关eigen thinu的问题

Assertion failed: ((!(m_computeThinU || m_computeThinV) || (MatrixType::ColsAtCompileTime==Dynamic)) && "JacobiSVD: thin U and V are only available when your matrix has a dynamic number of columns."), function allocate, file /usr/local/include/eigen3/Eigen/src/SVD/JacobiSVD.h, line 640.
出现这样的错误是什么原因呢 求指教 谢谢

这是断言错误,应该是你这个矩阵的U和V值都是0
