I used the wrong cut and paste here: there ought to be another line
prior to the print lines:
  local mopt_unpack = string.unpack('l',block)

As an aside, I'm expecting MOPT to be 0000, not 0001. value ought to be 15.

I can write a valid MAT file going the other way using 'd' as a write
formatter; but it doesn't seem to play nice reading.
