% notes:
% Let A1=Nasa/nasa1824 and A2=Boeing/nasa1824.  A1 and A2 have the same 
% nonzero pattern.  A1 and A2 differ in value in only 386 entries out of
% 39208, and only in 21 columns of the lower triangular part;           
% tril(A(196:321,196:216)) and the same rows of the upper triangular    
% part.  The magnitudes of the entries in A2 in this region of the      
% matrix are all tiny, and have only 9 digits if printed in base-10     
% (unlike the other entries, which have full precision).  I suspect A2  
% (Boeing/nasa1824) is a corrupted version of A1 (Nasa/nasa1824).
