Dear Barry and Matt,

     Thanks for the replies, I am not doing anything in parallel. I
     should use MatSetValues with appropriate column and row indices.
     
     Actually, what I would like to do, I would like to set up a
     vectorset(rectangular) and assign to a block in a matrix. Is 
     there a vectorset that I could use directly to somehow put 
     these vectors directly into this set. And use this vectorset to
     set some part of a matrix.

     Thanks for the advice in advance.

     BR,
     Umut
