Ada library to read/write matlab files?

Ada library to read/write matlab files?

[mockturtle]

Dear.all,
the subject says everything. 
Are you aware of an available library to read/write matlab (binary) files? I tried googling around a bit (just a bit) without finding anything.  
As an alternative, something to read/write HDF or CDF (not netCDF since it requires a specific matlab package [if I remember correctly...]).  

I would like something "independent", that is, interfacing with other libraries (e.g., matlab API) is something I would rather avoid.

Regards

Riccardo

One suggestion could be:
* get cdf35_0-dist-all.tar.gz from
    http://cdaweb.gsfc.nasa.gov/pub/software/cdf/dist/cdf35_0/w32/src_distribution/

* Compile and install that library
* make a small c-file containing "#include <cdf.h>"
* compile that file with 
     g++ -c -I 'path to cdf includes' -fdump-ada-spec
* and magic there is an cdf_h.ads.
     Given that the gcc you are using is modern.

I am not a Matlab user, but I know it can handle FITS files. So you might want to give a try to my library AdaFITS:

https://github.com/ziotom78/adafits

However, I am not sure it will fit your needs, as it has the following caveats:

1. It requires CFITSIO to be installed, so it is not "independent". However, CFITSIO is available in binary form for a variety of platforms.
2. It only reads ASCII/binary tables, there is no support (yet) for reading/writing images.
3. It requires an Ada2012 compiler (but I think should be trivial to make it work with an Ada2005 compiler, and it is definitively something I'll eventually fix).

Maurizio.

P.S. I too am interested in HDF5 bindings for Ada. I have already generated thin bindings using the gcc's trick suggested by Per Sandberg, but I surely will put some more work in them in order to make them easier to use.

Dear Maurizio,
Dear Per,
thank you for your replies and suggestions.  Unfortunately, my constraint of having a pure Ada solution was fairly strong (for reasons too long to explain here), so  I "throw together" a solution good enough for me.  

I am making it available through launchpad and I insert here a shameless link to it :-) 

         https://launchpad.net/adamant

in case in the future someone will search through the newsgroup again.

Currently it is very limited (but you can copy it! :-)  [did you get the joke? no?!? Then, what are you doing in this newsgroup? :-) :-) :-) ]  
It allows you only to write Matlab files and only matrices of double (of any dimensionality) and strings.  Cells, structs and reading are for a future release (maybe) 

It requires Ada 2012 since I spotted the occasion of using a dynamic predicate  (too cool!).  If you want to use it with a non Ada 2012 compiler, just go to the specs of Matlab.IO and remove the predicate from Matlab_Name.
