yes, actually.
Now:

Code:


#cas
rootsOfOne(n):=
BEGIN
RETURN e^(2*PI**range(n)/n);
END;

rootsOfZ(z, n):=
BEGIN
RETURN z^(1/n) * rootsOfOne(n);
END;

#end

it works, but I get first a warning "Recursive" (see attached images).
Then, trying with "3+4i" I get a little square in the matrix (second item): I don't know what's the reason...
