Write a user$-$defined MATLAB function $($function m$-$file$)$ for the following function:

z space equals space fraction numerator $3$ x squared y over denominator $3$ x squared plus y squared end fraction

The inputs to the function are x and y$,$ and the output is z$.$ Name the function as q$2\_$func. Write the function such that both x and y can be vectors.

Use the function q$2\_$func to calculate and display the value of z for x$=1$ and y$=3.$

Use the function q$2\_$func to calculate and display the values of z for x $=[17]$ and y$=3.$

Use the function q$2\_$func to calculate and display the values of z for x $=[17]$ and y$=[13]$
