I am doing a GUI which plots a cube when the user enters the dimension of the cube. But If i keep entering new dimensions, the old cube still stays at the display? Is there any way to delete the previous figure every time when new data is entered?

Without seeing your code I don’t know what you’ve already done. Perhaps the drawnow function will do what you want. (There are links to its friends at the end of that page and in the menu to the left of the text in the online documentation page.)

This is the sub function which gets executed when I enter the dimension of the cube(In the GUI).

case 'cube'
          a = str2double(get(handles.cubedimension,'string'));
          fm = [1 2 6 5; 2 3 7 6; 3 4 8 7; 4 1 5 8; 1 2 3 4; 5 6 7 8];
          vm = [0 0 0; a 0 0; a a 0; 0 a 0; 0 0 a; a 0 a; a a a; 0 a a];
          patch('Vertices',vm,'Faces',fm, 'FaceVertexCData',hsv(6),'FaceColor','flat'); 
                  %set default view
          az = wrapTo360(-37.5); el = 30; %limits for az 0...360  for el 0...90
          view(handles.axes1,[az el]);
          set(handles.Horizontalslider,'value',az/360);
          set(handles.Verticalslider,'value',el/90);
          axis([0 a*1.25 0 a*1.25 0 a*1.25]);
