function C = cs_add (A,B,alpha,beta)					    %#ok
%CS_ADD sparse matrix addition.
%   C = cs_add(A,B,alpha,beta) computes C = alpha*A+beta*B,
%   where alpha and beta default to 1 if not present.
%
%   Example:
%       Prob1 = UFget ('HB/ibm32') ;        A = Prob1.A ;
%       Prob2 = UFget ('Hamrle/Hamrle1') ;  B = Prob2.A ;
%       C = cs_add (A,B) ;
%       D = A+B ;                           % same as C
