protobuf-matlab - FarSounder's Protobuf compiler for Matlab Copyright 2011 FarSounder, Inc. http://code.google.com/p/protobuf-matlab/
This package provides a Matlab code generator for version 2.4.1 of Google's Protocol Buffers compiler (protoc) as well as support libraries for the generated Matlab code.
Get the protobuf source: svn co http://protobuf.googlecode.com/svn/tags/2.4.1 protobuf
Get the protobuf-matlab source: git clone https://code.google.com/p/protobuf-matlab/
Add the protobuf-matlab src files to the Google Protobuf src: cp -r protobuf-matlab/src protobuf
Compile the modified protobuf project.
This should yield a protoc executable with a --matlab_out option. You can now use protoc to generate Matlab reading and writing code for your .proto file(s).
In order to use the generated Matlab code, you'll need to add the protobuflib directory to your Matlab path. protobuflib is a collection of .m utility files used by the generated code.
