Write a Matlab function mySevenNorm that takes as input a matrix A and returns the "entry$-$wise" $7-$norm of the

matrix $($see Problem $2).$ Problem $2$:Consider the following matrix A and it's inverse A$^(-1),$

A$=[[0,1,0],[2,0,0],[0,1,1]],$A$^(-1)=[[0,0\mathrm{.}5,0],[1,0,0],[-1,0,1]].$

Let the "entry$-$wise" $7-$norm of a m$\backslash$times n matrix B $($or vector$)$ be defined as

$||$B$||\_(7,7)=(\backslash$sum$\_($i$=1)^$m $\backslash$sum$\_($j$=1)^$n $|$b$\_($ij$)|^(7))^((1)/(7))$
