In a function description, the name of the function being described appears first. It is followed on the same line by a list of parameters. The names used for the parameters are also used in the body of the description.
Here is a description of an imaginary function
foosubtracts x from y, then adds the remaining arguments to the result. If y is not supplied, then the number 19 is used by default.foo (1, [3, 5], 3, 9) ⇒ [ 14, 16 ] foo (5) ⇒ 14
More generally,foo (w, x, y, ...) == x - w + y + ...
Any parameter whose name contains the name of a type (e.g., integer or matrix) is expected to be of that type. Parameters named object may be of any type. Parameters with other sorts of names (e.g., new_file) are discussed specifically in the description of the function. In some sections, features common to parameters of several functions are described at the beginning.
Functions in Octave may be defined in several different ways. The category name for functions may include another name that indicates the way that the function is defined. These additional tags include
