Does anybody know a way to convert Matlab code into Fortran and then compile Fortran mex dll file for Matlab 2006a?
I want to ask three questions regarding Fortran and Matlab interface. The
two tools I am using are: Intel Visual Fortran 10.1 and Matlab 2006a.
Q1. What is the best converter to convert Matlab code into Fortran code with
readability? My understanding is that Fortran and Matlab are both vectorized
and they should be pretty similar and such converter should do a good job.
Q2. Is there a wizard for Intel Visual Fortran under MS Visual Studio.Net
2003 or Visual Studio.Net 2005 to set up environments for building mex dll
file for Matlab on Windows XP? There is such a wizard tool for...how can FORTRAN save .mat files for Matlab?
I have a question about the interface of Matlab. I read some books
about the interface, but I never success in doing this. So who can
tell me the basic step: how can I program to save the variables of
Compaq Visual Fortran90 file to a .mat file for Matlab7 use? Please
give me the details.
Thank you very much.
Have you read the part about reading/writing mat files in the external
interfaces part of the doc? there are all the necessary routines listed.
all you'll have to do, is either write interface blocks (fortran 90/95)
or declare the functions as external to use them.
Mic...Fortran 90 MAT FIle I/O module
Rather new to fortran 90. Luckily in the past All i've had to do is
make a few modifications here or there and get the code to compile and
interface with C. So, I've decided to write a module to interface to my
MAT File I/O library in C. Alas, I have limited access to fortran
compilers/knowledge. I have gotten some of it to compile with
gfortran/ifort on linux. Haven't tested gfortran on windows. I have
had problems with g95 and memory. It seems to hose up the C
malloc/calloc routines since those calls get wrapped through the g95
routines. I have in the past removed...Writing Matlab MAT files in Fortran on Crays
I recently received access to a nice Cray and I'd like to begin using
it ASAP. However, I've run into a significant problem: Right now, I
use MATLAB's MAT file format for data storage and it is wholy
unsupported by Mathworks on Crays...for even the most basic input &
output functions. Why do they ignore Crays? I don't know, but I need
to find a workaround ASAP.
First off, I am not a programmer. I am a chemical engineer. I've seen
the MAT file format and it would take me months to write a bug-free
bit stream reader & writer in Fortran. I ...converting fortran files to matlab files

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:

Many robust and efficient routines for matrix algebra and ODE/PDE
solvers are available
as open sourse FORTRAN codes such as ODEPACK,
LSODA etc. Has anyone tried to use it in tandem
with MATLAB or translate them into MATLAB?
Particularly, I'm interested in Gear method
for stiff/nonstiff ODEs.

I would like to know whether
watcom fortran compiler can be used to
run fortran mex files in matlab.
But we do support other FORTRAN compilers (see the above link for details).

I'm currently trying to run the fengdemo.f on Linux (Ubuntu). Compiling
goes well using the provided engopts.sh script:
mex -f engopts.sh fengdemo.f
But when I try to run ./fengdemo, I always get the message:
Can't start MATLAB engine
So apparently when the program tries to call engOpen("matlab "),
something goes wrong. In there anyway to dig deeper into this problem?
Any help would be greatly appreciated,

I manage to make fortran 90 mex-files by calling fortran subroutine already compiled in a distinct object file (sub.o).
I would like now make the same but from "my own true library" (made with modules in fortran90) compiled in a archive (.a) with they module files (.mod).
I do not find the way to make it. I mean, how to call library (made with modules fortran90) from fortran mex-files.
Anyone have an idea, how it is possible to do that?
PS: This library works fine for any fortran developer who make call it.

Dear Matlab programers,
I need to read data in files up to 1 million lines of 80 characters.
In order to make it fast, i try to use fortran with MAT files
I get no compilation problem (using MEX) but at execution i get the
following message :

Can someboby please help.
I am programming in Fortran77 and using the Salford compiler. I have
a number of questions
1) When I create the required data can I easily link up with Matlab to
use the graphics facilities. If the aswer is yes then can someone
please tell me how to do it.
2) If yes to question 1) then what format must the fortran data be
in for Matlab to recognise it.
3) Can I make use of the MEX approach for fortran 77 using the
salford compiler . If yes then can someone please tell me how to do
it or point me to a suitable reference
Many thanks in advance
