I used Tom Rondeau's changeset 7848 and applied it to my current updated code.
Currently I am getting a runtime error from ofdm sampler saying that there are "insufficient output ports".

Has anyone faced a similar issue? Esp. for OFDM over air, this is a major prob.

Hello all,

       I've been working with a colleague who works mostly in MATLAB to
prototype and test the work we're doing, so I've written a block that
uses the MATLAB engine interface to execute MATLAB code as part of a
flowgraph. It's based on the howto-write-a-block example, and can be
built and used in much the same way. Please let me know if you find this
block useful and if you needs other versions (for floats, etc.). If
you're interested in using this block, please follow the README.
       Since there is a translation to the MATLAB engine and back, this block
is significantly slower than a straightforward C++ block. I'd strongly
recommend using it with something like gr_head or "small" data streams.

It is located at:

I've left most of the licensing and doc stuff alone since I'm not sure
how to best modify it. Please let me know if this is an issue.
