Lion is not designed to be installed standalone. You could only upgrade from Snow Leopard.
My system was also upgraded from Snow Leopard; but the system became really slow after upgrading. So I decided to perform a clean installation. But I don’t want to re-install Snow Leopard and then upgrade.
After research, I found it not that hard to install Lion directly.
First you need a 8Gb flash drive or SD card. (I used SD card.)
Make a bootable drive from the DMG file you have. Please refer to

http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from-a-usb-flash-drive/

Reboot your system and hold option key. Boot from your flash drive.
Use Disk Utility to erase your HD.
Install Lion.

That’s it!

Enjoy your clean Lion.

The title is quite award. Hehe. A couple of days ago, I planned to use QT to build some stuff. But I found it counld not find “make” cmd on my snow leopard. I searched a lot; but only found Qs, no As. Some suggested to install XCode (which gives your OS “make”). But I have already installed the latest Xcode.  How come?

At last, I re-installed Xcode. And it works now!

I notice that there wasn’t “make” cmd in my /usr/bin/ path, but one in /Developer/usr/bin/. So I even tried to add a ~/.bash_profile with “export PATH=$PATH:/Developer/usr/bin/” to use make in Terminal. But QT Creator still didn’t work. After I re-installed XCode from the Snow Leopard Disc. I got “make” back inside /usr/bin/.

1. Add an “Axes” control on GUI. Change its tag to “axes_img”.  %% Tag in matlab GUI programming is used as function of name.
2. Change property of "Axes” visible to “off” to avoid it appearing like an axes in the GUI before image is loaded.
3. In some functions, like a button clicked, add code similar as below
   axes(handles.axes_img); % use the axes you put on GUI
imshow('filename'); % display the image

Then an image is loaded where you put the axes control when you click the button.
