# spatial_hub_connection_impl

Connection to a keyed_representation target layer from a spatial_representation source layer. Sets the input of the target to the unnormalized (i.e., not divided by length) spatial coding match of the source layer output to the ideal spatial code given by converting the corresponding unit vector on the target layer to the spatial representation of the source. Some relevant parameters are parameters of the spatial representation.

## Parameters

    parameter	default_value
    excitation	1
    inhibition	0

## share_lookup

    some_sphc share_lookup other_sphc

Attach `some_sphc` as another source of the target of another spatial_hub_connection `other_sphc` and share cacheing data regarding the ideal spatial code between the two. The attachment will be to port 0.
