# GLN , GLOG

## Purpose:

Generates a natural logarithmic series
(base e) in accordance with the specified parameters.

## Syntax:

GLN(length, spacing, factor, offset)

GLOG(length, spacing, factor, offset)

length |
- |
An integer, the length of the output series. |

spacing |
- |
A real, the spacing (delta x) between each
point on the x-axis. |

factor |
- |
Optional. A real, the
expansion factor along the x-axis. Defaults to 1. |

offset |
- |
Optional. A real, the
offset along x-axis, specified in radians. Defaults to 0. |

## Returns:

A series.

## Example:

gln(100, 0.1, 2, 5)

creates a logarithmic series of 100 points
spaced 0.1 x-units apart. This series is also be shifted by five x-units
(the offset value) on the x-axis, and compressed by a factor
of two.

glog(100, 0.1, 2, 5)

same as above.

## Remarks:

The formula used to generate each point,
*n*, in the series is as follows:

y[n] = log(spacing*factor*(n-1)
+ offset)

GLN and GLOG are identical.
