Fircls1
Webfircls1 uses an iterative least-squares algorithm to obtain an equiripple response. The algorithm is a multiple exchange algorithm that uses Lagrange multipliers and Kuhn-Tucker conditions on each iteration. References [1] Selesnick, I. W., M. Lang, and C. S. Burrus.

http://matlab.izmiran.ru/help/toolbox/signal/fircls1.html Webfir1 implements the classical method of windowed linear-phase FIR digital filter design [1]. It designs filters in standard lowpass, highpass, bandpass, and bandstop configurations. By default the filter is normalized so that the magnitude response of the filter at the center frequency of the passband is 0 dB.
