% notes:
% The YOUNG*C matrices originally appeared in the Harwell/Boeing     
% collection as type CSA (complex symmetric).  However, both upper   
% and lower triangular parts are present in the original files       
% (an invalid specification; only the lower part can be present      
% in the file).  If the entries in the upper triangular part are     
% considered as part of the matrix, the matrices become unsymmetric. 
% The matrices have been corrected in the UF Sparse Matrix Collection
% by changing their type to CUA so that the entries in the original  
% files are not ignored.  In addition, the YOUNG3C matrix has a zero 
% imaginary part, and thus appears here as a real matrix.
