$\%$ Create a $10$ array named a$1$ containing the values $8\mathrm{.}5,7\mathrm{.}7,0\mathrm{.}0,5\mathrm{.}5,4\mathrm{.}2,8\mathrm{.}0,$ and $9\mathrm{.}1.$ Use direct entry to create the array.

a$1=$

$\%$ Create a $10$ array $($row vector$)$ named z$50$ containing fifty zeros. Use MATLAB's built in zeros function to create the array.

$z50=$

$\%$ Create a $1D$ array named a$2$ containing the values from $0\mathrm{.}0$ to $25\mathrm{.}0$ with an increment of $0\mathrm{.}1.$ Use the MATLAB colon operator to crea

$a2=$

$\%$ Use an indexing operation to extract and save element $4$ of the array a$1.$ The result should be saved in the array a$3.$

a$3=$

$\%$Use an indexing operation to extract and save elements $12$ through $18$ of the array a$2.$ The result should be saved in the array a$4.$
