Passing arguments to functions, MATLAB in Engineering

Passing arguments to functions:

In all these functions examples faraway, at least one of the arguments was passed in the function call to be the value(s) of the equivalent input argument(s) into the function header. The technique used has been the call-by-value method of passing the values of the arguments to the input arguments in the functions.

In some situations, though, it is not essential to pass any arguments to the function. Consider, for illustration, a function which simply prints a random real number with two decimal places:
