Is it possible to generate a GUI on Raspberry Pi with Simulink and RPI Support package?

Hi! I am quite new to programming Raspberry Pi by Simulink, but it makes a lots of fun :)
Actually I want to create a real standalone application for my Raspberry Pi. So the measured data / digital in and outs will be displayed through the HDMI monitor and i can control digital i/o's by the USB hardware which is connected to my Rasperry Pi.
I am using raspberry pi 2, matlab 2015 with installed raspberry pi support package.
Thank you for your help in advance :D

I have recently used MATLAB to update the firmware on my SD card for Raspberry Pi 3 Model B as I want to build a standalone model in Simulink. Now when I try to use it with a monitor, I am not able to access the Desktop GUI. startx command doesn't seem to work. And even on using raspi-config to change Boot Options to Desktop GUI, it says to install lightdm. But since I couldn't configure WiFi or Ethernet from the command line, I could not install lightdm. So, does that mean it is not possible to access Desktop GUI if the SD card has been updated through MATLAB and not NOOBS?

The image provided by MathWorks is based on Raspbian Jessie Lite. This is a lite version of the Raspbian Jessie image. One of the differences with this image is that it is headless and does not have a Desktop GUI.
If you require a Desktop for your Raspberry Pi, you will have to install a few packages. Follow the instructions below to set up the Desktop:
1. Set up your Raspberry Pi with the Raspbian image provided by MathWorks.
2. Install the following packages to get the GUI interface:
sudo apt-get update
sudo apt-get install --no-install-recommends xserver-xorg
sudo apt-get install --no-install-recommends xinit
sudo apt-get install --no-install-recommends raspberrypi-ui-mods lxterminal gvfs
Please refer to for an explanation of the above commands.
3. Connect the HDMI monitor cable, USB camera and keyboard to Raspberry Pi and then reboot the Pi.
4. A login prompt will appear on the monitor (normal black screen – without GUI). Enter the credentials “pi” & “raspberry”
5. Enter “startx” to the prompt using the keyboard and this will show the GUI interface on the monitor.
If you have problems connecting your Raspberry Pi to the network, you may follow these instructions:

The question was to develop an GUI that can read the measured data and display it on the GUI. Not about the desktop GUI. My requirement is same as above. Develop a GUI using simulink and deploy it to raspberry pi so that the GUI fetches the realtime value and displays it on the screen.

You can use an SDL Video Block to do the display; see
If you program everything in Simulink then you can deploy to Raspberry .

SDL Video block requires 3 parameters as input, YCbCr or RGB format. How can we develop a GUI on Simulink and connect it to the 3 inputs of the SDL Video Display Block.

why are you being so lame matlab. this is something you really need in your library to make this program more useful for developing programs.
