        %HPMIN   Construct a HPMIN object.
        %   H = HPMIN(Fstop,Fpass,Astop,Apass,Fs) constructs a minimum-order
        %   highpass filter specifications object.
        %
        %   Fstop is the stopband-edge frequency and must be a positive scalar
        %   between 0 and 1 if no sampling frequency is specified or between 0 and
        %   Fs/2 if a sampling frequency Fs is specified.
        %
        %   Fpass is the passband-edge frequency and must be a positive scalar
        %   greater than Fstop and between 0 and 1 if no sampling frequency is
        %   specified or between 0 and Fs/2 if a sampling frequency Fs is
        %   specified.
        %
        %   Astop is the minimum stopband attenuation in dB. It must be a positive
        %   scalar.
        %
        %   Apass is the maximum passband deviation in dB. It must be a positive
        %   scalar.
        %
        %   Fs is the sampling frequency. If Fs is not specified, normalized
        %   frequency is assumed. If Fs is specified, it must be a positive scalar.
