You should not give image snippets.....copy the code here...along with your input.

[Steven Lord]

In your first example, it expects you to define a variable named f (that should probably contain a function handle.)

In your second example, you need to pass into that function some input arguments. The help text (that large block of comments at the start of the code) describes what those input arguments represent and what conditions they have to satisfy.
