Is it possible Matlab shows the grid on the surface of the plot?

close all;

X=-10:.1:10;
T=-10:.1:10;
%i=1;
w0=1;
c=-1;
mu1=.4*1i;
a=2*mu1.^2-(2*w0.^2);
[x,t]=meshgrid(X,T);
u=2*(1i*mu1.*x-(1i*mu1*c./(a)).*t);
r1=-4*1i*mu1*sin(u);
surf(x,t,abs(r1));
shading flat;
%grid off;
view(-48,68)

[KALYAN ACHARJYA]

Change the faceAlpha (within 0 and 1) value, see, it may heps you (This is transperancy)

surf(x,t,abs(r1),'FaceAlpha',0.5);

Or Try this one:

X=-10:.1:10;
T=-10:.1:10;
%i=1;
w0=1;
c=-1;
mu1=.4*1i;
a=2*mu1.^2-(2*w0.^2);
[x,t]=meshgrid(X,T);
u=2*(1i*mu1.*x-(1i*mu1*c./(a)).*t);
r1=-4*1i*mu1*sin(u);
h=surf(x,t,abs(r1));
shading interp;
set(h,'edgecolor','m')
% Similarly you can change the face color also for more visible.
view(-48,68)

Answer 2

[Walter Roberson]

X=-10:.1:10;
T=-10:.1:10;
%i=1;
w0=1;
c=-1;
mu1=.4*1i;
a=2*mu1.^2-(2*w0.^2);
[x,t]=meshgrid(X,T);
u=2*(1i*mu1.*x-(1i*mu1*c./(a)).*t);
r1=-4*1i*mu1*sin(u);
h = surf(x,t,abs(r1));
shading flat;
%grid off;
view(-48,68)
h.EdgeColor = 'k';

However, you have so many edges in this plot that when you turn the edges back on, the entire plot will look black.
