Create a $1$D 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.

Create a $1$D array $($row vector$)$ named z$50$ containing fifty zeros. Use MATLAB's built in zeros function to create the array.

Create a $1$D 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 cre

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

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$4.4$ necessary indices for the operation.
