Yes, I do it quite frequently. The following is written using Matlab 5.3, Compaq Visual Fortran 6.6, and Windows 2000. The example here uses Fortran95 source, though this can be done in FORTRAN77 just as easily.\u00a0There are examples of MEX files that use MKL:\u00a0vvmult_mkl.f90<\/a>, IMSL:\u00a0vvmult_imsl.f90,<\/a>and CXML:\u00a0vvmult_cxml.f90<\/a>.<\/span><\/p>\n

First, you will need to modify your mexopts.bat file. On R13 (v6.5) modify the file c:\\matlab6p5\\bin\\win32\\mexopts\\df66opts.bat. On R11 and R12, you will need to issue the commandprefdir(1)<\/span> to tell you where your mexopts.bat is located. You can see my mexopts.bat file forR11\/R12<\/a> and\u00a0R13 <\/a>at these links.<\/p>\n

In order to add IMSL, you will need to add the following lines to your mexopts file:<\/p>\n

set LINKFLAGS=%LINKFLAGS% sstatd.lib sstats.lib
\nset LINKFLAGS=%LINKFLAGS% smathd.lib smaths.lib sf90mp.lib
\nset LIB=%LIB%;%DFDir%\\IMSL\\LIB;<\/span><\/p>\n

For MKL, you will need to add these lines, you must also uncomment one of the last three lines to specify the processor type. Note that MEX files linked against mkl_p4.lib will only run on a P4. MEX files linked against mkl_p3.lib will only run on a P3 or P4.<\/span><\/p>\n

set LINKFLAGS=%LINKFLAGS% mkl_s.lib mkl_lapack.lib
\nset LIB=%LIB%;C:\\Program Files\\Intel\\MKL\\ia32\\lib
\nrem ********************************************************************
\nrem Choose One (p4=Pentium 4, p3=Pentium 3, def=all others)
\nrem ********************************************************************
\nrem set LINKFLAGS=%LINKFLAGS% mkl_def.lib
\nrem set LINKFLAGS=%LINKFLAGS% mkl_p3.lib
\nrem set LINKFLAGS=%LINKFLAGS% mkl_p4.lib<\/span><\/p>\n

For CXML, add the following lines:<\/span><\/p>\n

set LINKFLAGS=%LINKFLAGS% cxml.lib
\nset LIB=%LIB%;%DFDir%\\CXML\\LIB
\nset INCLUDE=%INCLUDE%;%DFDir%\\CXML\\INCLUDE<\/span><\/p>\n

Note that many of the routines in these libraries conflict. Many conflict across all 3 libraries, in fact. Therefore, if you think that you might be using different libs on different projects, you can also leave all of the LINKFLAG variables commented, and specify the libraries on the command line. So if you want to use MKL, you build the file with the command<\/span><\/p>\n

\u00bb mex\u00a0vvmult_mkl.f90 mkl_s.lib mkl_def.lib mkl_lapack.lib<\/span><\/p>\n

Likewise, the syntax for IMSL is:<\/p>\n

\u00bb mex\u00a0vvmult_imsl.f90 sstatd.lib sstats.lib smathd.lib smaths.lib<\/span><\/p>\n

And finally, CXML:<\/span><\/p>\n

\u00bb mex\u00a0vvmult_cxml.f90 cxml.lib<\/span><\/p>\n

And there you go!<\/p>\n
