------------------- Demos: solution of LS problems
Demos:
Demo_Vandermond.m  % test orthogonalization methods on a Vandermond matrix
Demo_CGLS.m        % calls cgls and lsqr for well1033 and illc1850
--> lsqrSOLtest.m from the web, needs sone fixes
--> Explanations for lsqrlsqrSOLREADME

Algorithms:
MGS_qr.m   % QR with Modified Gram-Schmidt
cgls.m     % CG-Least Squares algorithm
lsqrSOL.m  % LS-QR algorithm          


Data: Matrices from Matrix Market
 mmread.m            % read matrices from Matrix Market
 well1033.mtx	     % wellconditioned matrix 
 well1033_rhs1.mtx   % rhs for wellconditioned matrix
 illc1850.mtx	     % illconditioned matrix   
 illc1850_rhs1.mtx   % rhs for illconditioned matrix
