documentation/example for MATLAB usage?

Hi,

I had an old code that used libdai for creating a factor graph and running belief propagation. Now that I am using libdai-0.3.2, I am not able to run the same code now.

I get the error:

Undefined variable "libdai" or class

"libdai.FactorGraph".

Error in fnCrfSegmentationv8 (line 69)

fg = libdai.FactorGraph;

It looks to me that the syntax has changed with subsequent versions.

This is what I do in my code:

fg = libdai.FactorGraph;  %line 69 fnCrfSegmentationv8.m

...

...

for nodeInd = 1 : nNodes

        fg.push(nodeInd, unaryVal(nodeInd, :)');

end

...

...

for edgeInd = 1 : nEdges

    ...

    fg.push([node1 node2], pairwiseVal);

end  

....

....

R = fg.infer('BP');

Is it possible to read somewhere such that I can know how to define my factorgraph and use it properly?

Thanks & Regards,
