Create a flowchart for a MATLAB program that will be named Test$1$Prob$3$ that:

a$)$ uses the colon operator $($ : $)$ to create a $4$ by $3$ array that looks exactly like the following.

$15913$

$1513119$

$12141618$

b$)$ Then use an array function$($s$)$ to compute the median value of all the elements of the array and

store the value in a variable named cmedian.
