$(5$ pts$)$ Write a Matlab function f $=$ randnum$($a$,$b$)$ which takes as input two integers

a and b$,$ and generates and returns a random integer that is equally likely to take any

value between a and b $($inclusive$).$ Save this function in the file randnum.m$.$

$($b$)(5$ pts$)$ Write a Matlab m$-$file test$\_$randnum.m that tests the accuracy of your randnum$()$

function. This program should use randnum$()$ to generate $100,000$ random numbers be$-$

tween $1$ and $10.$ Store each random number in a vector x $($it will be of length $100,000$ when

the simulation is done$).$ Then display a histogram of the results using the hist$($x$,1$:$10)$

function
