%                                 ADA = getada1(ADA, A,Ajc2,perm, d, blkstart)
% GETADA1  Compute ADA(i,j) = (D(d^2; LP,Lorentz)*A.t(:,i))' *A.t(:,j),
%   and exploit sparsity as much as possible.
%   Ajc2 points just beyond LP/Lorentz nonzeros for each column
%   blkstart = K.qblkstart partitions into Lorentz blocks.
%
%   IMPORTANT 1: only LP and sparse Lorentz part. PSD part ignored altogether.
%   For Lorentz, it uses only det(dk) * ai[k]'*aj[k].
%   IMPORTANT 2: Computes ADA only on triu(ADA(Aord.lqperm,Aord.lqperm)).
%     Remaining entries are set to 0. (CAUTION: sparse(ADA) will therefore
%     destroy the sparsity structure !).
