Hallo everyone!

I wonder which analytical function (if someone exists) is used in the
animate speed n function in text command.

I know the argument n of the function is a real between 0 and 1 and it
grows roughly exponentially as a function of n.

I was trying to fit the curve, but I didn't find the right analytical

Does someone know the analytical function used in vmd to change the
speed using animate speed n?
