How to control SSD1306 128X32 OLED display in matlab?

I want to display text on SSD1306 128X32 OLED display using matlab. I have the matlab and simulink support package for arduino already but I cannot find any documentation regarding the control of above mentioned display. I connected the display to matlab via arduino uno, made object named dev and tried various things but nothing seems to work. It will be helpful if anyone can show me how to print 'HELLO WORLD' on the display.

>> a=arduino()

a = 

  arduino with properties:

                  Port: 'COM4'
                 Board: 'Uno'
         AvailablePins: {'D2-D13', 'A0-A5'}
  AvailableDigitalPins: {'D2-D13', 'A0-A5'}
      AvailablePWMPins: {'D3', 'D5-D6', 'D9-D11'}
   AvailableAnalogPins: {'A0-A5'}
    AvailableI2CBusIDs: [0]
             Libraries: {'I2C', 'SPI', 'Servo'}

>> dev = device(a,'I2CAddress','0x3C'); % display object
>> write(dev,[hex2dec(81) hex2dec(FF)]); % controlling the contrast

this code works in my board for turning display on:

>> a = arduino('COM7','mega2560','Libraries','I2C');
>> dev = device(a,'I2CAddress','0x3c');
>> writeRegister(dev,0x00,0xaf,'uint16');

What should i have to do if my OLED display is 0.96"? same code?

It is not size dependent, you have to care about slave address of your display
