%CS_DROPTOL remove small entries from a sparse matrix.
%   C = cs_droptol(A,tol) removes entries from A of magnitude less than or
%   equal to tol.  Same as A = A .* (abs (A) >= tol).
%
%   Example:
%       Prob = ssget ('HB/arc130') ; A = Prob.A ;
%       cspy (abs (A) >= 1e-10) ;
%       C = cs_droptol (A, 1e-10) ;
%       cspy (C) ;
