I have three column vectors Xm, Ym and Zm. I plotted these vectors as below code:
k = boundary(Xm,Ym,Zm,1);
trisurf(k, Xm,Ym,Zm,'edgecolor','none','facecolor','m', 'facealpha',0.5)
I got a object by above code. I want to smooth the surface of this 3-d object

Can you share output figure?

sir this is the output figure of vectors Xm, Ym and Zm using boundary function

Are you looking for something like this?
dt = delaunayTriangulation(Xm,Ym) ;
t = dt.ConnectivityList ;
x = dt.Points(:,1) ;
y = dt.Points(:,2) ;
F = scatteredInterpolant(Xm,Ym,Zm) ;
z = F(x,y) ;
trisurf(t,x,y,z,'EdgeColor','k')

sir, i want to smooth the straight edges and angular corners i.e. roughness of geometry which is getting from Xm, Ym and Zm..

i searched about smoothness..In matlab, 'smooth', 'smooth3', 'sgolayfilt' and 'smoothdata' functions are used for smoothing the figure.. I cant observe that the which function will be giving the best and how much smoothness in result..
