plot 3 d square

hi

this script must plot a square, but i got the attached plot, how to connect all lines?

thanks

vhat1=[x,repmat(2,length(y),1),repmat(2,length(z),1)];
vhat2=[(x),repmat(-2,length(y),1),repmat(2,length(z),1)];
vhat3=[repmat(2,length(x),1),y,repmat(2,length(z),1)];
vhat4=[repmat(-2,length(x),1),y,repmat(2,length(z),1)];
vhatt=[vhat1;vhat2;vhat3;vhat4];
