Not THAT much of a beginner. :) A true beginner thinks Latex is something you find in rubber gloves. :)

h1=title('$y = \frac{1}{x+1}$');set (h1,'Interpreter','latex');
>> h1
h1 = 
  Text ($y = \frac{1}{x+1}$) with properties:

                 String: '$y = \frac{1}{x+1}$'
               FontSize: 11
             FontWeight: 'bold'
               FontName: 'Helvetica'
                  Color: [0 0 0]
    HorizontalAlignment: 'center'
               Position: [0.500000638346518 1.00401459854015 0.5]
                  Units: 'data'

  Show all properties

                Visible: on

If you want to see all the properties, get gives you an expanded list.

Now, you can change a property on the fly using a simple assignment.

>> h1.FontSize = 18;
>> h1.Color = 'r'
h1 = 
  Text ($y = \frac{1}{x+1}$) with properties:

                 String: '$y = \frac{1}{x+1}$'
               FontSize: 18
             FontWeight: 'bold'
               FontName: 'Helvetica'
                  Color: [1 0 0]
    HorizontalAlignment: 'center'
               Position: [0.500000638346518 1.00656934306569 0.5]
                  Units: 'data'

And now the title is as I set it.

thank you, sir! very helpful!

And very good humour, too! I am a beginner, indeed. You see, 20 days ago i thought Mathcad Prime 3.1 was better than Matlab. You see now, i have a good sense of humour as well.
