Re: [Discuss-gnuradio] PMT: vector of vectors of ints

[West, Nathan]

AFAIK that's only used for coloring and sanity checking sizes before running a flowgraph. You should be able to use your matrix datatype with a vlen of  your total matrix size.

<type>float</type>

<vlen>N*M</vlen>

Is there any way to create a vector of vectors of ints with the PMT library?

I'm trying to make a C++ GR block that takes in an NxM matrix.  For GRC all the types are listed at the link below, none really fit my model.

https://github.com/gnuradio/gnuradio/blob/d4bb541ec1ec93446ecfa53948a1a6f995fffb64/grc/core/Param.py#L303

What are my options for passing a matrix into the block?

Thanks,

Devin
