The norm of a complex number can be obtained by abs() command.

Maybe Anindya G is asking how to generate random vectors from a uniform distribution on a Euclidean ball of radius R, centred at 0, in Euclidean space of dimension N. In Anindya G's case, R=2. The condition that the vectors are complex correspond to N even.
