%CONVERTOLDNET Convert pre-2.3 release MLP and MDN nets to new format
%
%	Description
%	NET = CONVERTOLDNET(NET) takes a network NET and, if appropriate,
%	converts it from pre-2.3 to the current format.  The difference is
%	simply  that in MLPs and the MLP sub-net of MDNs the field ACTFN has
%	been  renamed OUTFN to make it consistent with GLM and RBF networks.
%	If the network is not old-format or an MLP or MDN it is left
%	unchanged.

%	See also
%	MLP, MDN
