% OPNML/MATLAB4 routines - provided for backward compatibility
%
% Provided to resolve existing references to MATLAB4 argument syntax:
%
% BELINT4    compute shape function information for a FEM domain
% DRAWELEMS4 draw FEM element configuration 
% EL_AREAS4  compute triangular finite element areas
% LCONTOUR2  obsolete; use lcontour4
% LCONTOUR4  contour a scalar field on a FEM grid.
% LOADGRID4  load principle gridfiles for a given domain name (input)
% PLOTBND4   plot boundary of FEM mesh
% VECPLOT2   routine to plot vectors.  
%
% Not yet ported, but still functional
% GENBEL4    build a boundary element file (.bel) for QUODDY.
% ISOPHASE   contour a vector of scalar (phase) values on a FEM grid.
% TELLIPSE   plot ellipses from amp/phase specification of a vel field
