 function [R,lag] = xcov1(X, Y, biasflag)

+//Calling Sequence
+//[R, lag] = xcov (X)
+//... = xcov (X, Y)
+//... = xcov (..., maxlag)
+//... = xcov (..., scale)
+//Parameters 
+//X: Input vector
+//Y: if specified, compute cross-covariance between X and Y, otherwise compute autocovariance of X.
+//maxlag: is specified, use lag range [-maxlag:maxlag], otherwise use range [-n+1:n-1].
+//scale:
+//     'biased': for covariance=raw/N,
+//     'unbiased': for covariance=raw/(N-|lag|),
+//     'coeff': for covariance=raw/(covariance at lag 0),
+//     'none': for covariance=raw
+//     'none': is the default. 
+//Description
+//Compute covariance at various lags [=correlation(x-mean(x),y-mean(y))]. Returns the covariance for each lag in the range, plus an optional vector of lags.
