 if P == 1
   A = [0 0 0];
   B = [1 0 0];
   C = [0 1 0];
   D = [0 0 1];
   E = [0 1 1];
   F = [1 0 1];
   G = [1 1 0];
   H = [1 1 1];
   P = [A;B;F;H;G;C;A;D;E;H;F;D;E;C;G;B];
   axis([-2 2 -2 2 -2 2])
   plot3(P(:,1),P(:,2),P(:,3),'g'), hold on
   roll = 2*pi; pitch = 2*pi; yaw = 2*pi;
   dcm = angle2dcm(yaw, pitch, roll);
   P = P*dcm;
   axis([-2 2 -2 2 -2 2])
   plot3(P(:,1),P(:,2),P(:,3)) % rotated cube
   axis([-2 2 -2 2 -2 2])
   plot3(0,0,0,'or')
   xlabel('X')
   ylabel('Y')
   zlabel('Z')
   grid on
 elseif P==2

I am creating a cube with this code, and as P changes, i want to move cube in x direction with increment of 1. How to perform this operation.? I tried to move, but previous lines remains as it is, and it becomes rectangle..!

Create a hgtransform() and parent everything to be moved to it. Then when it is time to move it, set its transform matrix, which you can do directly or you can use (for example)

Txy = makehgtform('translate',[-1.5 -1.5 0]);
set(t2,'Matrix',Txy)

I checked, and object is moving at its axis.!

I want to shift my cube by 1 w.r.t its position..! As well my object is square.

 clear all;clc
ax = axes('XLim',[-15 15],'YLim',[-15 15],'ZLim',[-15 15]);
view(3)
grid on
   A = [0 0 0];
   B = [1 0 0];
   C = [0 1 0];
   D = [0 0 1];
   E = [0 1 1];
   F = [1 0 1];
   G = [1 1 0];
   H = [1 1 1];
   P = [A;B;F;H;G;C;A;D;E;H;F;D;E;C;G;B];
   plot3(P(:,1),P(:,2),P(:,3),'g'), hold on
   roll = 2*pi; pitch = 2*pi; yaw = 2*pi;
   dcm = angle2dcm(yaw, pitch, roll);
   P = P*dcm;
t = hgtransform('Parent',ax);
Rz = eye(4);
Sxy = Rz;
for r = 1
    % Z-axis rotation matrix
    Rz = makehgtform('zrotate',r);
    Sxy = makehgtform('scale',r);
    % Concatenate the transforms and
    % set the transform Matrix property
    set(t,'Matrix',Rz*Sxy)
    drawnow
end
pause(1)
set(t,'Matrix',eye(4))

But the problem is that which will be the variable which will control my cube movement in this program to LEFT, RIGHT, UP, DOWN or HOME LOCATION-RESET ?
