Like in 2D plot we can use plot(X1,Y1,LineSpec1,...,Xn,Yn,LineSpecn) How can I plot multiple matrices in the same 3D plot?

It is my understanding that you would like to use surf/mesh to plot in 3D for multiple matrices in the same figure, just like plot(x1,y1,x2,y2,...) is used to plot() to plot a 2D plot for multiple matrices in the same figure.
You can use "hold on" to retain current plot when adding new plots. The following example will illustrate how to achieve the above:
[X1,Y1] = meshgrid(-10:.5:10);
R1 = sqrt(X1.^2 + Y1.^2) + eps;
Z1 = sin(R1)./R1;
[X2,Y2] = meshgrid(-5:.5:5);
R2 = sqrt(X2.^2 + Y2.^2) + eps;
Z2 = sin(R2)./R2;
m = surf(Z1)
hold on
surf(Z2)
Refer the Hold documentation for more information on how to use hold
