$($b$)$ Write a function $($m file$)$ takes an array and replaces and values outside of the

lower and upper ranges by $0.$ For example, the function could be used to remove

any invalid examination grades, where a grade could be less than zero or greater

than $100.$ Make use of the vectorisation capabilities of MATLAB, and therefore a

loop should not be required for the solution. Here are sample calls, along with the

output that should be generated.

rng$(100)$;

test $=$ randi$([-10110],4,5)$;

test$\_$val $=$ validate$\_$data$($test$,0,100)$;
