From: Bjørnar on 3 May 2010 07:29 I want to create a DLL from my MATLAB code for use in a FORTRAN project. Is it possible? From the documentation it seems that only C/C++ is supported? with regards Bjørnar Lund, Trondheim, Norway

From the documentation it seems that only C/C++ is supported? You need to know what you're doing to pull that sort of thing off. The problem is name mangling in object code. A function name 'f' in the sorce code is converted to something like '_f', 'f_' or '_f_' in the compiled object code. Since a DLL is a set of object code functions, you need to know exactly what happened to be able to call the correct name from your FORTRAN program. One of the problems with FORTRAN is that these kinds of things exist in any number of combinations, that depend on anything from OS to compiler to what other language you attempt to interface with. So you will have to do a lot of digging to find the relevant details. Apart from that, matlab is based on LAPACK, which used to be written with FORTRAN in mind. You might be better off calling the LAPACK library directly from your FORTRAN routines. Rune

I am currently using the Intel FORTRAN 10.0.025 compiler embedded in MSVS 2005. - Bjørnar

Also, since I depend on the bvp4c function it seems to me that using LAPACK is not an option. Bjørnar |
