Hi,

Is there an Eigen::VectorXd method equivalent to std::vector erase?

Thank You.

no but you can use vec.data() and vec.data()+vec.size() as begin/end iterators and then call conservativeResize...

I actually would like to remove the i-th element from an object of type Eigen::VectorXd. With the std::vector, I can just do

Code: Select all

my_vec.erase(my_vec.begin() + i)

but with Eigen, should I just write my own method. For example, just use something like

Code: Select all

copy(my_eigen_vec.data() + i + 1, my_eigen_vec.data() + my_eigen_vec.size(), my_eigen_vec.data() + i)

and then do a conservative resize.


Thank You.
