You may proceed like shown below.

nodes = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1068640/aaa_ele.txt','HeaderLines',1) ;  % read the nodal data
vert = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1068645/aaa_node.txt','HeaderLines',1);  % read the vertices data 
% Remove the last lines 
nodes(end,:) =[] ;   % last line has some text, remove it 
vert(end,:) = [] ;   % last lines has some text, remove it ; 

t = table2array(nodes(:,2:4)) ;    % nodal connectivity data 
p = table2array(vert(:,2:3)) ;    % coordinates/ vertices 
 triplot(t,p(:,1),p(:,2)) ;   % plot the mesh

So you want to use triangle_display...?
