Write a function named myFun whose inputs are a function $f$ and a positive integer $n.$ The function will return the value of ${\displaystyle \underset{=1}{\overset{n}{}}}[f(){]}^2.($You may assume the function $f$ can operate on matrices.$)$

The following is an example of how your function would be used in the command window:

$f=e(x)5^{**}x$;

$$ myFun $(f,3)$

ans $=$
