%LDLSOLVE solve LDL'x=b using a sparse LDL' factorization
%
% Example:
%   x = ldlsolve (LD,b)
%
% solves the system L*D*L'*x=b for x.  This is equivalent to
%
%   [L,D] = ldlsplit (LD) ;
%   x = L' \ (D \ (L \ b)) ;
%
% LD is from ldlchol, or as updated by ldlupdate or ldlrowmod.  You must
% not modify LD as obtained from ldlchol, ldlupdate, or ldlrowmod prior
% to passing it to this function.  See ldlupdate for more details.
