 Usage

Global variables are shared variables that can be seen and
modified from any function or script that declares them. The
syntax for the global statement is

    global variable_1 variable_2 ...

The global statement must occur before the variables appear.


 Example

Here is an example of two functions that use a global
variable to communicate an array between them. The first
function sets the global variable.

       set_global.m


  function set_global(x)
    global common_array
    common_array = x;

The second function retrieves the value from the global
variable

       get_global.m


  function x = get_global
    global common_array
    x = common_array;

Here we exercise the two functions

  --> set_global('Hello')
  --> get_global

  ans =
  Hello
