        Hello every body out there !

        Let me introduce myself : I am Yoann LE BARS and I am a fresh Boost 
user. I am french too, so please excuse my bad english.

        I have got a problem with Boost uBlas, I hope it is the good list to 
post about it. I have made a little exemple which show what is my 
problem (it compiles but I found the behaviour very strange) :

        Here is a version which works but do not satisfy me :

        Why does it not satisfy me ? Well, because I am fulling a sparse matrix 
with an identity matrix, the A matrix and the transposed A matrix : it 
is very redondant and A can be a very big matrix.

        That is the reason why I have make the LeastSquareMatrix class. I 
believe I have done something wrong in it, but what ?

        Best regards.

                                        Yoann LE BARS,
                                        alias Le Farfadet Spatial
