After the "make" in this directry has been finished, the test can be made by:
        % sh all-test.sh
which will generate the data files:
       ATTEN_*.DAT, EXPND_*.DAT, POLES_*.DAT AND TBL_*.DAT.

  The files ATTEN_*.DAT are the data files for the Unix plot program "xgraph"
to plot the attenuation functions of the filter by the formula.
You can view all of them by:
     % xgraph ATTEN_*.DAT
or view separately.

  The files EXPND_*.DAT are the data files for the Unix plot program "xgraph"
to plot the attenuation functions of the filter by using the fractional 
expansion with the calculated poles and their coefficients.
 You can view all of them by:
     % xgraph EXPND_*.DAT
or view separately.

  The files POLES_*.DAT are the data files for the Unix plot program "xgraph"
to plot the complex poles of the attanuation function of the filter.

  The files TBL_*.DAT are the data files in the style of Fortran90
which gives the complex poles whose imaginary parts are positive
and their coefficients of the fractional expansion.
