Global function is a kind of stand alone function, consisting of a function name followed by a parenthesis.  In side the parenthesis are arguments, if any.  For example,

                           ->a = sin((x + y) / 0.45)

Here "sin" is a global function, whose arguments, inside the parenthesis, must be of numerical data type.  If the number of arguments or data type of the arguments are not agreeable to those predefined by the function, an error message is reported.

It is worthwhile to note that all class names are global functions, for example

                           ->A = Matrix(2,3)

Here "Matrix" is a global function, whose job is to define a Matrix object, and assigned to a variable "A".  Details of global functions that define objects are in class and class function.
