Thread Subject: File conversion: fortran to matlab

Hello

I have gone through google search, other forums and similar
message posted here also. I have not got really a way to
convert f90 file to matlab file. Its really a big file.
Can anyone please help me?

Thanks.

I just did it today, on a 300 line file, by hand. If you
know Matlab, Fortran isn't that much different I don't
think. Just copy and paste, do some rearranging and
relabeling, and you're done. Really, I have no Fortran
training at all and I figured it out in less than an hour.

I did have to use the online Fortran reference at IBM a
couple of times to find out the syntax of the IF statements,
DO loops, etc. It still wasn't that bad.

As an alternative to converting over the file, you may be able to write a
wrapper to make this into a MEX-file:

The third and fifth items could be useful for you.

Converting Fortran to MATLAB can sometimes be
straightforward, but a *lot* of Fortran stuff has no
direct translation to MATLAB, particularly some of the
newer F90/F95 stuff. You would need to understand
Fortran's pass-by-reference behavior (Fortran purists,
don't bite me on this please!) vs MATLAB's pass-by-value
for function calls, etc. when doing the translation. If
you don't know Fortran very well this could be a rather
large task for you to undertake. And if you have a very
big file as you indicate, then I would take Steven Lord's
suggestion and look into making it a mex routine. Several
people on this ng can help you with that if care to go
that route. Do you have a Fortran compiler available?
