Question

I have the following problem: I want to simulate some control engineering system. As it is quite complicated I used the computer to derive some (complicated) equations which can only be exported to fortran77 code. On my development pc this is no problem (linux machine).

No I want to do it in hardware and here I have to use a windows OS. Unfortunately matlab does not support gfortran on windows. Therefore I can not compile the fortran files on that box.

My idea was now to translate to C as a C compiler is available at matlab on win. Any other (better) options?

I have several SUBROUTINES in the manner of the following.

      SUBROUTINE sys_rhs (x, v, dx, param) 
      REAL*8 x(6)
C     code is coming here
      RETURN
      END SUBROUTINE

Is it good practice and does it work to use the function sys_rhs__ in the interface function written in C?
The problem is, that I can not test it as I do not have massive access to the windows machine. So it should work if I try it and I should not need to experiment a lot.

Also what lib’s do I need on windows? Where can I get them?

Thanks
Christian

Answer 1

The answer was quite simple: I had some syntax errors in my fortran code. gfortran does no such strict syntax checking and therefor interpreted the fortran code correctly. After removing the typos I succceded transcoding with f2c.
