Reconstructs the first (downpass) nodal reconstructions

Reconstructs the preliminary nodal set for all characters for a particular node. This function is called over a postorder sequence of internal nodes where left and right descendants are known. Because this function needs to be fairly high-performance, it does not do much checking for parameter validity, thus unsafe usage of this function might not be caught. It is up to calling functions to ensure that the appropriate parameters have been set before use.

Usage

mpl_first_down_recon(node_id, left_id, right_id, morphyobj)

Arguments

node_id

The index of the node being reconstructed.

left_id

The index of the left descendant.

right_id

The index of the right descendant.

morphyobj

An instance of the Morphy object.

Value

The integral parsimony length (right now)
