Question $4.($m file$)$ Write a function

function y$=$nonsense$($x$)$

defined in a $.$m file that should return $0$ if is odd and otherwise $($so is $16,$ while is $0).$ Now test this function by using printstuff from the question above using the values $[4,11,15,20]($this is part $1$ of hw$01$q$4.$m$).$

Finally $($this is part $2,$ also in hw$01$q$4.$m$)$ create a plot for x from $0$ to $50$ of the function $.$ Change the style so that the line is dashed and the points are marked with a symbol. Include a legend, a title, and the axis labels $\text{'}$x$\text{'}$ and 'nonsense'.

Hint: look up in the MATLAB help. You will probably need a for loop to evaluate for plotting, because only operates on a single number.
