adversarial change vector

[sigasserethz]

Is there a memeberfunction of eigen to remove a specific element, or to add a element at a specific place? I tried shifting values around with for loops and using conservativeresize, but this is to slow to run on my computer.

not I'm aware of but how about switching the element you want to remove to the end of the vector and conservativeResize(current size - dim)? and when you add something just append it to the end?
