function val = r8crs_zeros ( n, nz, row, col )

%*****************************************************************************80
%
%% r8crs_zeros() zeros an R8SR matrix.
%
%  Discussion:
%
%    The R8CRS storage format stores the nonzero entries of row I in 
%    entries ROW(I) through ROW(I+1)-1 of VAL.  
%    COL(J) records the column index of the entry in VAL(J).

%
%  Input:
%
%    integer N, the order of the matrix.
%
%    integer NZ, the number of nonzero elements.
%
%    integer ROW(N+1).  The nonzero offdiagonal elements 
%    of row I of A are contained in A(ROW(I)) through A(ROW(I+1)-1).
%
%    integer COL(NZ), the column indices of the nonzero elements of A.
%
%  Output:
%
%    real VAL(NZ), the nonzero elements of A.
%
  val = zeros ( nz );
