I am hoping that the c gurus can help me understand how OpenMx matrices
are stored, updated and passed around.

Here is the situation:
We are trying design data-structures for the block-sparse BLAS routines
and are struggling with the issue of ownership of "double" matrices. Our
key data-structure is called the "blockSparseMatrix". For example, there
may be a huge "factor-loading" matrix where each dense sub-block would
map on to one or more OpenMx parameter matrices. In the ordinary
factor-model, each dense sub-block would point to the single

Now that the closed beta is released we can get back to the categorical outcomes estimation. What is the status and expected completion date on the backend? Are there front end issues that need to be dealt with?
