A $47$ matrix $G$ has been created for you.

Extract the $33$ submatrix of $G$ consisting of columns $3$ through $5$ and rows $1$ through $3$ and store it in the matrix $H,$ that is$,$ create a matrix $H=\left[\begin{array}{ccc}{G}_{13}& G_{14}& G_{15}\\ G_{23}& G_{24}& G_{25}\\ G_{33}& G_{34}& G_{35}\end{array}\right]$ by extracting the appropriate rows and columns from the matrix $G.$

Create the matrix $E$ obtained from $H$ by replacing the current value of $H_{13}$ with $100.$ Do not enter $E$ explicitly. Hint: enter first $E=H$; to create a copy of the matrix $H$ and then manipulate the matrix $E.$

Create the matrix F obtained by deleting the second column of the matrix $H.$ Do not enter $F$ explicitly. Hint: enter first $F=H$; to create a copy of the matrix $H$ and then manipulate the matrix F$.$ Make sure you delete the column and not extract a submatrix.

Don't forget to include your name as a comment in the script.
