Hello everyone. I have a vector composed of some positive and negative numbers. Is there is simple way to quickly get the three cube roots for all the components in the vector. So if A is the vector with N values, then is there a function (or some methods) that replies a 3*N matrix for the cube root of each component. Thanks a lot!

You could use the exp sin cos formula for roots
