function [ zmat, seed ] = c8mat_uniform_01 ( m, n, seed )

%*****************************************************************************80
%
%% C8MAT_UNIFORM_01 returns a unit pseudorandom C8MAT.
%
%  Discussion:
%
%    The angles should be uniformly distributed between 0 and 2 * PI,
%    the square roots of the radius uniformly distributed between 0 and 1.
%
%    This results in a uniform distribution of values in the unit circle.
