Hi all, I would like to understand what exactly happens when jit.bfg is filled with a matrix as an input. So far, my understanding is that the values inside the cells of the input matrix will evaluate the values for the output matrix of the jit.bfg.

I don't exactly get how it works when the input matrix has 2 planes and jit.bfg only one. Are the two planes kind of used as x and y inputs of the jit.bfg, but resulting in a single scalar output?

Any help is greatly appreciated, I attach a patch as an example:
