function c = cs_counts (A,mode) %#ok
%CS_COUNTS column counts for sparse Cholesky factor L.
% c = cs_counts(A) returns a vector of the column counts of L, for the
% Cholesky factorization L*L' = A. That is, c = sum(spones(chol(A)')),
% except the Cholesky factorization is not computed.
% c = cs_counts(A), returns counts for cs_chol(A).
% c = cs_counts(A,'col'), returns counts for cs_chol(A'*A).
% c = cs_counts(A,'sym'), same as cs_counts(A).
%
% Example:
% Prob = ssget ('HB/bcsstk01') ; A = Prob.A ; c = cs_counts (A)
% full (sum (spones (chol (A)')))
