Trigonometry
Octave provides the following trigonometric functions. Angles are
specified in radians. To convert from degrees to radians multipy by
pi/180
(e.g. sin (30 * pi/180) returns the sine of 30 degrees).

Each of these functions expect a single argument. For matrix arguments,
they work on an element by element basis. For example,
sin ([1, 2; 3, 4])
=> 0.84147 0.90930
0.14112 -0.75680
| atan2 (y, x)
|
Mapping Function |
|
Compute atan (y / x) for corresponding elements of y
and x. The result is in range -pi to pi.
