This function returns the estimated delay between two input signals using crosscorrelation.
D = FINDDELAY(X,Y), returns estimated Delay D between X and Y. D is positive implies Y is delayed with respect to X and vice versa. If X, Y are matrices, then D is a row vector corresponding to delay between columns of X and Y
D = FINDDELAY(...,MAXLAG), uses MAXLAG as the maximum correlation window size used to find the estimated delay(s) between X and Y:
> If MAXLAG is an integer-valued scalar, and X and Y are row or column vectors or matrices, the vector D of estimated delays is found by cross-correlating (the columns of) X and Y over a range of lags -MAXLAG:MAXLAG. > If MAXLAG is an integer-valued row or column vector, and one input is vector and another be matirx (let X is a row or column vector , and Y is a matrix) then the vector D of estimated delays is found by cross-correlating X and column J of Y over a range of lags -MAXLAG(J):MAXLAG(J), for J=1:Number of columns of Y. > If MAXLAG is an integer-valued row or column vector, and X and Y are both matrices. then vector D of estimated delays is found by cross-correlating corresponding columns of X and Y over a range of lags -MAXLAG(J):MAXLAG(J).
By default, MAXLAG is equal to MAX(LX,LY)-1 for vectors,
