function C = cs_droptol (A, tol) %#ok
%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) ;
