 This directory contains two utilities:

 calc_bands.c : Calculates the bands coefficients based on hard
 			    coded options and writes them to the iir_cf.h file
				Example of use:

				#./calc_bands

 fit.c		  : Calculates the coefficients of a quadratic equation
 			    best-fitting the data points given in the 'data' file.
				The format of the data file is one line per point
				with the following format:

					X Y ERROR

				Example of use for three points: 

				#./fit 3 < data

				This small program is used to map the values passed by
				the sliders, which range from -20.0 to 20.0 to the range
				of values required by the IIR filters.

These two utilities require the GNU Scientific Library (GSL) to work.
