There is indeed a change in arguments to calls to Blas or Lapack functions on 64 bit platforms.

See http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/hel... "MEX-Files Calling BLAS or LAPACK Functions Must Be Updated On 64-Bit Platforms"

I will change the mex sources expanding the mechanism we put in place for the pointers across different Matlab versions. Hopefully over the week-end.
