Hi,

I use a ublas::vector for caching some data between threads. One of my  
threads sould write data into a position of the vector and the other  
thread should be read the data. In some cases more than one thread can  
write to the vector on the same position. Every thread that sets the  
data creates the same data, so it is irrelevant which thread writes.

Are ublas::matrix and ublas::vector for reading and writing on the  
same indexposition thread-safe?
If they are not, how can I make them thread-safe?

Thanks

Phil
