R = COMPLEXROOTS(X,N) returns all (N) complex Nth roots of X.
X can be a real or a complex number, or an array of such numbers; N must be a natural number.
If X is scalar, COMPLEXROOTS(X, N) is a 1*N vector
with all complex Nth roots of X.
If X is a vector of length M, COMPLEXROOTS(X, N) is a M*N matrix
with all complex Nth roots of X along the second dimension.
If X is an array of dimension D, COMPLEXROOTS(X, N) is an array
of dimension D+1 with all complex Nth roots of the elements of X
along the last dimension.
To cross-check the result: complexroots(x,n).^n
To plot the result in the complex plane (for scalar X):
plot(real(r),imag(r),'.'), a=1.2*abs(r(1)); axis([-a a -a a]),grid on
