You'll most likely have to give up on having the structure definition
stored in this file. (I think) the best you will be able to do is stuff
the data into a file in a known order then read it out and construct
your structure on the other side. I recommend XDR because it is so
simple (although I haven't created XDR files in IDL and read them in
MATLAB so who knows what could crop up). There isn't built in support
for MATLAB but libraries are available. Here's one:
http://crppwww.epfl.ch/~moret/matlab/local.html
and there are others. Java based XDR libraries would be trivial to use too.
As someone mentioned, XML is an option is your structures aren't too
"heavy". There are a number of XML parsers on the MATLAB central file
exchange that will read an XML file into a structure but you would still
need to write a function in IDL that would write the XML file to their
specific formats. Probably easier to go the XDR route.
