hi, I would like to know whether watcom fortran compiler can be used to run fortran mex files in matlab. Thanks Sunnam No. http://www.mathworks.com/support/solutions/data/1-19F84.html?solution=1-19F84 But we do support other FORTRAN compilers (see the above link for details).

Dear Matlab users, I am trying use to Watcom fortran compiler to run fortran-mex files in matlab. I cannot run the files as the watcopts.bat file of Matlab supports only c-mex files to run on matlab. Is there any way i can run fortran-mex files to in Matlab. I suppose some changes have to be made to watcopts.bat file like to change the compiler and linker options. Any suggestions of how to do these changes. Thankyou Himabindu ...

Dear All, I'm trying to link matlab and fortran with mex files and engine matlab, in linux OS. My general purpose is the following: 1) a matlab script A calls a mex function B based upon fortran source code 2) mex function B calls another function in matlab C within matlab engine 3) matlab routine C calls another mex file in fortran D While i'm able to do steps 2) and 3), I can't do step 1). Before to show the code, please reply to this simple question: Is it possible to build the overall process 1-3? On 8 Okt, 16:37, "Michele Catalano" <cata...@yahoo.it> wr...

Hi, does anyone know why Fortran-mex files can't be compiled on matlab V5.3 and run on matlab V6? For example: if I compile the example-program (shipped with matlab) timestwo.f on matlab version 5.3 (R11) and try to run it on matlab version 6+ (R12 or R13), I get the error message: "Unable to load mex file: E:\timestwo.dll. The specified module could not be found. ??? Invalid MEX-file" Likewise if I compile it on matlab version 6.1 (R12), I get a similar error message if run on matlab version 5.3 (R11). However, if I run it on matlab version 6.5 it works OK. ...

I have some algorithms implemented with fortran(alg.f) on Unix system. These fortran code with c code gateway file (alggateway.c) can be compiled as mex file on Unix system (mex alggateway.c alg.f). NOw I want recompile these code on windows system because these code had good documentations. I have some problems when I am struggling with these code. 1.Using 'mex -setup', I can only choose one compiler. If i choose fortran compiler, 'mex' wont understand *.c file, vice versa. On windows system, can I compile using command 'mex alggateway.c alg.f'. 2. I am t...

hi there all, i was wondering if it would be easy or possible to coverting fortran files into matlab files. i have some data that was created in fortran but i really need to work on that data in matlab, i m using matlab version 6.5. if anyone knows and can point me in the correct direction, i would be very grateful, Thank u for ure time Tapan Hi, You have to write mex files : Read this : <http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/ch06engi.html> J�r�me I don't understand.......

Hello, I am currently trying to pass a structured array from a matlab program to a fortran program using a MEX layer in matlab. The fortran program will be called a number times since it is embedded in a loop in the matlab program. I am trying pass two lengthy structured arrays ('s' and 'par'). I am able to compile the fortan program and the mex shell in matlab, but when I execute it I recieve an error in matlab of a segmentation fault, which I think is because the structured array values are replaced by zeros when being passed from matlab into fortran. Therefore, ...

Hello everyone, novice MEX programmer here, so please excuse my inexperience. I'm trying to pass a cell array of strings from matlab into a fortran mex file, and ultimately assign that data into a fortran variable full of strings that will be used in a pre-existing fortran subroutine. So, within matlab, I have something like: strings{1}='100' strings{2}='50' strings{3}='301' (Notice that the string lengths are dissimilar in general, which makes the cell array useful in this case.) I then take those strings, and pass them into a mex-function that I am wri...

Hi, I have some Fortran code that I am trying to incorporate into MATLAB routines. This code has gotos, common blocks, etc... Is there a way to compile this code into a mex file? The file I'm interested in compiling has a bunch of subfunctions (no main program). My hope is to use these subfunctions as functions in MATLAB. If this is not possible, do you have any suggestions for incorporating this code into MATLAB... or am I stuck rewriting it? Thanks!
