1. OBJECTIVE: f2matlab.m is a small translator which aims to
convert Fortran90 files to Matlab m-files.
1) Matlab is becoming ubiquitous in the engineering and scientific
communities for its ease of use coupled with its powerful
libraries. Yet the fact remains that a large number of stable and
dependable programs exist in the fortran77/90 corpus.
2) Many times, often amidst the porting of fortran programs to
Matlab, an automated converter of fortran90 code to Matlab code would
3) Having written matlab2fmex.m, a matlab to fortran90 mex file
converter, the writing of f2matlab, which performs the reverse
conversion, was substantially simplified.
3. BUG REPORTS and WISH LIST:
For all bug reports, a wish list for f2matlab, and suggestions,
or email email@example.com
4. F2MATLAB CAPABILITIES: f2matlab is aimed at converting
Fortran90 code to Matlab m-files. Accordingly, only basic data types
and constructions are recommended. f2matlab can handle:
all numeric types (handled by Matlab interpreter)
most string functions
comparisons, branches, loops, etc.
basic read/write/print statements (if it's not too fancy...)
5. F2MATLAB LIMITATIONS: f2matlab can not handle some features of
fortran90 yet. These include:
can't handle complex read and write statements
6. HOW TO USE F2MATLAB: f2matlab expects a single fortran90 fortran file to
convert. If you have fortran77 code, use some free converter
(e.g. to_f90 by Alan Miller) before running f2matlab. Then simply
call f2matlab by using the full filename:
The output will be filename.m in the same directory.
A few flags are available that effect conversion:
% want_kb=0; 1 ==> if keyboard mode is desired after some conversion steps
% want_ze=0; 1 ==> direct f2matlab to zero all array variables.
% want_fi=0; 1 ==> direct f2matlab to try to put fix()'s around declared integers.
Multiple subroutines and functions can and should be in the same fortran90 file.
