TITLE Plot Title Function

Section: Handle-Based Graphics

Usage

This command adds a title to the plot. The general syntax for its use is 
  title('label')

or in the alternate form 

  title 'label'

or simply 

  title label

Here label is a string variable. You can also specify properties for the label, and a handle to serve as a target for the operation 

  title(handle,'label',properties...)

Example

Here is an example of a simple plot with a title. 
--> x = linspace(-1,1);
--> y = cos(2*pi*x);
--> plot(x,y,'r-');
--> title('cost over time');
Warning: Newly defined variable nargin shadows a function of the same name.  Use clear nargin to recover access to the function

which results in the following plot.

We now increase the size of the font using the properties of the label 

--> title('cost over time','fontsize',20);
