Hi,

  This might be trivial question, but I need to construct a compressed_matrix from 
CSR / CSC triplets. 
At the moment I'm using a nested for loop and using push_back, 
but this is very slow. There has to be a faster way of constructing the sparse 
matrix object from the CSR triplets. Any ideas ?
