You need to first load your mat file with the load() function

if exist('image.mat', 'file')
  % Load image from mat file.
  storedStructure = load('image.mat');
  % Get the image.
  yourImage = storedStructure.yourImage;
  % yourImage is whatever you called your image when you saved your mat file.
  % Display it.
  imagesc(yourImage);
  % Get rid of the goofy default colormap
  colormap(gray(256));
else
  msgbox('File does not exist.');
end
