How to smooth my 3d plot,i tried smooth function but it only works for 2dimensional.
Y is a 201x201 matrix
Y= [201 201]
x = 10:0.1:30;
z = 1:0.01:3;
[X,Z] = ndgrid(x,z);
mesh(X,Z,smooth(Y))

Have you tried conv2?

Sorry, I'm not sure how to use it, i got an error following an example.
x = 10:0.1:30;
z = 1:0.01:3;
[X,Z] = ndgrid(x',z);
mesh(conv2(X,Z,(Y_3D)))
Error using conv2
The first and second arguments must be vectors when the third argument is a matrix.
