Generates a cotangent series in accordance with the specified parameters.
GCOT(length, spacing, frequency, phase)
|
length |
- |
An integer, the length of the output series. |
|
spacing |
- |
A real, the spacing (delta x) between each point on the |
|
frequency |
- |
Optional. A real, the frequency specified in cycles per second (Hertz). Defaults to 1. |

Optional. A real, the phase specified in radians. Defaults to 0. |
A series.
gcot(100, 0.1, 2, 5)
creates a cotangent series of 100 points spaced 0.1 x-units apart resulting in 20 cycles in the series. The series is also be shifted by five units (the offset value) on the x-axis, and compressed by a factor of 2.
The formula used to generate each point, n, in the series is as follows:
y[n] = 1/TAN(2π • frequency • spacing • (n-1) + phase)
