function a = r8ci_zeros ( n )

%*****************************************************************************80
%
%% R8CI_ZEROS zeros an R8CI matrix.
%
%  Discussion:
%
%    The R8CI storage format is used for an N by N circulant matrix.
%    An N by N circulant matrix A has the property that the entries on
%    row I appear again on row I+1, shifted one position to the right,
%    with the final entry of row I appearing as the first of row I+1.
%    The R8CI format simply records the first row of the matrix.
