But I don't know boost library well enough, where what types are defined, etc. Someone else has to take good care of these things Web如果x是浮點數的非本征向量,我可以通過以下方式將其映射到eigen::MatrixXf. MatrixXf x_cen=Map(*x,*n,*p); 但是,由於共享內存,對x_cen修改也將報告給x 。 我想要的是避免這種情況。 我想將x深度復制到eigen::MatrixXf x_cen ,以確保對x_cen所做的更改不會報告給x 。 那怎么辦?
