dear list,
         i am more or less a Newbie at using ublas for sparse operations and i would love a little advice on some delicate questions.
 
in particular i would like to work with a sparse matrix in which all of the single terms are vectors or matrices instead of double. All the containers are templated matrices which implies that i am free to do it nevertheless...
 
how can i make the library to know how to perform the multiplication between all of the different terms? the case is for example of a SparseMatrix of Matrices to be multiplied by a vector of vectors.
 
Similarly i would like to create a matrix doing something like A = trans(B)*B  (i think it is called Symmetric Product)... is it available in ublas?
 
finally i would like to know what is the relation of ublas to GLAS
 
thanks in advance
