Dear List,
       i guess this has already being addressed a few time but i can not
find the link ...

i'd like to ask what is the "good" (read FAST) way of setting to zero
all the entries of a compressed matrix without touching its structure?

the function i am using now is :

inline static void SetToZero(compressed_matrix<TDataType>&
rA){std::fill(rA.value_data().begin(), rA.value_data().end(),

unfortunatelly valgrind is telling me of something wrong happening when
i do this... indeed the error could come from somewhere else but it
always appear here in my application.

right now i am using 1.33.1 which i guess is getting more and more
outdated...i think this is a good occasion to ask about the ublas
did any "major" change happen in the interface for the forthcoming 1.34
release? what will be the areas of open development in ublas in the next
years? is anyone working in parallelism ?

greetings from spain
