Reduce edgewidth in trisurf plot

Good morning,

for a publication I produced the attached plot using the trisurf command. I'd like the two current distributions with its colours to look more exposed, but the edges of the triangular mesh prevent the colours to be visible more clearly (unfortunately, the mesh must be included in the plot and can't be made coarser). Is it possible to reduce the edgewidth of the triangles or apply some other method to create a better plot?

Thank you very much for your help!

x = rand(100,1) ;
y = rand(100,1) ;

dt = delaunayTriangulation(x,y) ;

t = dt.ConnectivityList ;
p = dt.Points ;
d = sqrt(p(:,1).^2+p(:,2).^2) ; 
h = trisurf(t,p(:,1),p(:,2),d)  ;
h.LineWidth = 0.1 ;

I tried your solution, but the linewidth is not reduced in my plot!

x = rand(100,1) ;
y = rand(100,1) ;
dt = delaunayTriangulation(x,y) ;
t = dt.ConnectivityList ;
p = dt.Points ;
d = sqrt(p(:,1).^2+p(:,2).^2) ; 
h = trisurf(t,p(:,1),p(:,2),d)  ;
h.EdgeAlpha = 0.5 ;

Great, now it works fine, thank you!
