Now it looks like you're doing it more correctly. One problem remaining: you
can't read a complex type like a sparse matrix using HDF5. You have to use
jldopen. Again: complicated objects need JLD both for reading and writing. The
only things you can read/write with HDF5 are very simple numbers (Float64,
Int32, etc), Arrays of simple numbers, strings, and arrays of strings. That's
basically it. Use JLD for anything else.
Unfortunately, you can't use "hyperslab" indexing for sparse matrices. It's
something that libhdf5 only supports for dense objects. It's not at all
obvious how to make it work for sparse objects.
