corr_coeff (version 1.0)

This program reads a table of measurements from an input file where each column contains
the measurements for one variable and each row contains the measurements for one sample.
The linear correlation coefficient for each pair of variables is written in tabular form to
standard output.

See the manual for a more detailed description of this tool.
