Consider the following two vectors

x $=[0\mathrm{.}53771\mathrm{.}8339-2\mathrm{.}25880\mathrm{.}86220\mathrm{.}3188]$

y$=[-1\mathrm{.}3077-0\mathrm{.}43360\mathrm{.}3426]$

Find the output of xcorr$($x$,$y$)$ at the lag of $-1$:$$ ans$=$Answer $1$ Question $4$

Find the output of xcorr$($x$,$y$)$ at the lag of $2$:$$ ans$=$Answer $2$ Question $4$
