Works

sdpt3(blk,A,C,b,ops)

Fails

    I remembered now that this was expected, as the unsupported but massively used feature of manipulating input arguments in mex-files no longer is guaranteed to work (as it did in all former matlab version, albeit not officially). mexschur call in schurmat_sblk is one such example

    It looks like Kim fixed this in his release of SDPT3. We should incorporate that change.
