I am trying to plot independent planes in 3D space using one set of coordinates. For example:

clear all;
X = [0 1
    0 1];
Y = [0 0
    1 1];
Z = [1 1
    1 1];
X1 = [0 1
      0 1];
Y1 = [0 0
      1 1];
Z1 = [0 0
      0 0];
surf(vertcat(X, X1), vertcat(Y, Y1), vertcat(Z, Z1),'FaceColor','blue','edgecolor','none');

However, rather than producing separate planes, this produces a Z shape. Where am I going wrong, please?

Note that it must be possible to combine the coordinates into a single set so I can later use surf2stl. Therefore, I cannot just plot one using surf and then use hold on.

Thanks.

It seems vertcat is the problem. I plotted them separately here using hold (easier to write and debug if necessary), but you could combine them in one line if you want:

X = [0 1
    0 1];
Y = [0 0
    1 1];
Z = [1 1
    1 1];
X1 = [0 1
      0 1];
Y1 = [0 0
      1 1];
Z1 = [0 0
      0 0];
figure(1)
surf(X, Y, Z,'FaceColor','blue','edgecolor','none'); 
hold on
surf(X1, Y1, Z1,'FaceColor','red','edgecolor','none');
hold off
