Footnotes

(1)

The ‘#!’ mechanism works on Unix systems derived from Berkeley Unix, System V Release 4, and some System V Release 3 systems.

(2)

Comma-separated lists are also sometimes informally referred to as cs-lists.

(3)

Some of Octave's functions are implemented in terms of functions that cannot be called recursively. For example, the ODE solver lsode is ultimately implemented in a Fortran subroutine that cannot be called recursively, so lsode should not be called either directly or indirectly from within the user-supplied function that lsode requires. Doing so will result in an error.

(4)

It would be much better to use prod (1:n), or gamma (n+1) instead, after first checking to ensure that the value n is actually a positive integer.

(5)

The ‘.m’ suffix was chosen for compatibility with MATLAB.

(6)

For example, to first sort based on the values in column 1, and then, for any values that are repeated in column 1, sort based on the values found in column 2, etc.

(7)

The old versions of rand and randn obtain their initial seeds from the system clock.
