The following files were changed to create a MATLAB mex interface1) Add mex.cThis file contains the code for my interface.2) Changed MakefileAdded commands for compilation on an HP 9000/series 700.Made the MEX-file the default makefile target.3) Changed merge.c & merge.hThese were changed according to my desire for facet merging tocorrect the vertices. Code for this in 3 and higher dimensionsdoes not exist. These changes are not necessary for the MEX interface.4) set qh_RANDOMtype  to 4 in user.h.Richard SchreierDec 1995
