Consider the following two vectors

x $=[3\mathrm{.}03490\mathrm{.}7254-0\mathrm{.}06310\mathrm{.}7147-0\mathrm{.}2050]$

y$=[-0\mathrm{.}12411\mathrm{.}48971\mathrm{.}4090]$

Find the output of xcorr$($x$,$y$)$ at the lag of $-1$:$$ ans$=$Answer $1$ Question $20$

Find the output of xcorr$($x$,$y$)$ at the lag of $2$:$$ ans$=$Answer $2$ Question $20$
