How can I plot 2 matrices in the same 3D plot using surf or mesh?

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?

[John Chilleri]

plot3 is the the 3d version of plot, perhaps this will be of use!

Use hold on and plot use surf twice..

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
