Transform a column of continuous features that represent the mean of a von Mises distribution to n columns of continuous features. The number n represent the number of points to evaluate the von Mises distribution. The von Mises pdf is given by
f(x | mu, kappa, scale) = exp(kappa * cos(scale*(x-mu)) / (2*pi*Io(kappa))
and is only valid for x, mu in the interval [0, 2*pi/scale].
