IN MATLAB

Create your own function that returns the inverse of your inputs.

For example, if your input vector, $r,$ is equal to $3,4,5.$ The output of your function must be $[1/3\frac{1}{4}$

$\frac{1}{5}.$

Example:

$r=[345]$;

$>>b=$ your$\_$function$\_$name $(r)$;

$>>b$

$b=$

$0\mathrm{.}3333,0\mathrm{.}25,0\mathrm{.}2$

Given the vector $x=[1,8,3,9,0,1],$ using for loop create a short set of commands that will

Add up the values of the elements.

Create a $4-$by$-7$ array of random numbers $($use rand$).$ Move through the array, element by element,

and set any value that is less than $-0\mathrm{.}2$ to $0$ and any value that is greater than $($or equal to$)0\mathrm{.}2$ to $1.$

Given $x=[4,1,6]$ and $y=[6,2,7],$ compute the following arrays

a$)d_{ij}=\frac{x_i}{2+x_i+y_j}$

b$)e_{ij}=$ reciprocal of the lesser of $x_i$ and $y_j$
