function y_cum = cum2x (x,y, maxlag, nsamp, overlap, flag)
%CUM2X Cross-covariance
% y_cum = cum2x (x,y,maxlag, samp_seg, overlap, flag)
% x,y - data vectors/matrices with identical dimensions
% if x,y are matrices, rather than vectors, columns are
% assumed to correspond to independent realizations,
% overlap is set to 0, and samp_seg to the row dimension.
% maxlag - maximum lag to be computed [default = 0]
% samp_seg - samples per segment [default = data_length]
% overlap - percentage overlap of segments [default = 0]
% overlap is clipped to the allowed range of [0,99].
