25 Jan 2011 MEXING WITH IFORT 11.0 IN 64 BIT MATLAB FOR 64 BIT MATLAB IN WINDOWS MEXING WITH MATLAB 7.6 - 7.8 AND IFORT 11.0 Author: Leslie Foster

As pointed out in
http://www.mathworks.com/matlabcentral/newsreader/view_thread/283589

the type of nlhs and nrhs in Matlab's mexFunction should be int*4, even on a 64 bit computer. This means that changes are required in lupp.F and luppf.F. Line 38 of lupp.F should be changed to
      INTEGER*4 NLHS, NRHS
and line 25 of luppf.F should be changed to
      integer m,n,lda,ldl,ldu,ldp
      integer*4 nlhs
The original code worked in Matlab 7.8 but the correction is required for Matlab 7.9.

Also for lupp_mex.m to work with Matlab 7.9 (or greater, I presume, but have not tested) in lupp_mex.m the three occurrences of
version_num == 7.8
should be changed to
version_num >= 7.8).
