Question $1$: $(5$ marks$)$

Consider the following Matrix:

Write a matlab code to:

$A=\left[\begin{array}{cccc}1& 2& 5& -3\\ -3& 4& 0& -9\\ 2& -1& 7& 8\\ 5& 6& -2& 10\end{array}\right]$

$1-$Create the matrix $A$

$2-$ Create a matrix $B$ of size $41$ and whose rows contain the sum of the columns of matrix A$.$

$3-$ Find the solution of $A^{-1}x=B,x=A^{-1}B$
