Details:

Help list request noted that the bwmorph function produces an error.  Verified
that call with 'endpoints' results in:

error: bwmorph: unknown OPERATION 'endpoints' requested

lines 313-314 show:


#    case "endpoints"
#      ## not implemented


Adding this bug report as a feature/compatibility request. Matlab help does
not indicate what algorithm is used, but does give a graphical depiction of
what should happen, and mentions that it should follow a 'skel' operation (so
the Pratt reference might be of use).
