高阶累积量工具箱参数设定

liuchang777

下了高阶累积量的工具箱，但是有些参数不会设定，
function   y_cum = cum4est (y, maxlag, nsamp, overlap, flag, k1, k2)
%CUM4EST Fourth-order cumulants.
%       Should be invoked via CUMEST for proper parameter checks
%       y_cum = cum4est (y, maxlag, samp_seg, overlap, flag, k1, k2)
%       Computes sample estimates of fourth-order cumulants
%       via the overlapped segment method.
%
%       y_cum = cum4est (y, maxlag, samp_seg, overlap, flag, k1, k2)
%              y: input data vector (column)
%         maxlag: maximum lag
%       samp_seg: samples per segment
%        overlap: percentage overlap of segments
%          flag : 'biased', biased estimates are computed
%               : 'unbiased', unbiased estimates are computed.
%   k1,k2 : the fixed lags in C3(m,k1) or C4(m,k1,k2); see below
%   y_cum : estimated fourth-order cumulant slice
%           C4(m,k1,k2)  -maxlag <= m <= maxlag
%  Note: all parameters must be specified
这是工具箱前的参数，我做的是信号检测，用四阶累积量算法，不知道该怎样设定参数？
maxlag,overlap,
flag,samp_seg,k1,k2,
