How can a function have a vector as its default argument list?

edit

A function in a programming language can have a vector as its default argument list by defining the function with the vector as the default value for one or more of its parameters. The vector can be defined using the appropriate syntax for the programming language being used, and can be initialized with the desired values.

For example, in Python, a function could be defined with a default vector argument like this:

def my_function(param_1, param_2, vector_arg=[1, 2, 3]):
    # code for the function

Here, the my_function function has three parameters, with vector_arg being the third. This parameter has the default value of [1, 2, 3], which is a vector of three numbers.

When the function is called without specifying a value for vector_arg, the default value of [1, 2, 3] will be used. If a different value is passed in, such as [4, 5, 6], that value will be used instead.

The syntax and specific details for defining a function with a vector as a default argument list will vary depending on the programming language being used.
