How do I get two images to display top and bottom of screen in Matlab/Psychtoolbox? I can already do left and right sides.

Hi, I'm trying to display two images, one on the top, and one at the bottom of the screen in Psychtoolbox. I know how to do that already with the right and left sides of the screen. The code for that is below. Any advice would be appreciated!

[imageHeight,imageWidth,colorChannels]=size(ImageDataData);

      gap=100;
      leftRect=[xCenter-gap-imageWidth,yCenter-imageHeight/2,xCenter-gap,yCenter+imageHeight/2];
      rightRect=[xCenter+gap,yCenter-imageHeight/2,xCenter+gap+imageWidth,...
         yCenter+imageHeight/2];

The values are the x,y coordinates of the top right coordinates of the rectangle the x,y coordinates of the bottom left coordinate of the rectangle

    topRect = [xCenter-imageWidth/2, YCenter-gap-imageHeight, xCenter+imageWidth/2, Ycenter-gap];
    bottomRect = [xCenter-imageWidth/2, Ycenter+gap, xCenter+imageWidth/2, Ycenter+gap+imageHeight];
