I searched over the forum and it seems that I did not announce this package when it is initially created.
So here it is: https://github.com/JuliaSparse/SparseVectors.jl Simply put, it provides sparse vectors (not sparse matrices with one-column) and a series of methods operating thereon. Recently, I did a major upgrade of the package and many more functions are added. The package has been systematically tested and it is ready for general use. A majority of the functionalities will be migrated to Julia base, after Julia v0.4 is released. If your applications involve processing sparse vectors (e.g. text analysis), you may check it out and play with it. Cheers, Dahua
