# Description of the program: corr

This program computes the autocorrelation of a scalar data set.

## Usage:

corr [Options]

Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also - means stdin

Possible options are:

Option | Description | Default
--- | --- | ---
-l# | number of data to use | whole file
-x# | number of lines to be ignored | 0
-c# | column to be read | 1
-D# | number of correlations | 100
-o# | output file name | without file name: 'datafile'.cor (or stdin.cor if stdin was read) If no -o option is given stdout is used
-V# | verbosity level 0: only panic messages 1: add input/output messages | 1
-h | show these options | none

## Description of the Output:

The first two lines contain: 1. the average and 2. the standard deviation of the data. The following lines are the autocorrelations (first column: delay, second column: autocorrelation).
