I. Final Exam Practice Questions:

For the following $2-$D table, which code will output the maximum number of products from Product $2$ column. Assuming that the complete table is stored in a variable called $A.$

$\backslash$table$[[$Factory$,$Product $1,$Product $2,$Product $3],[1,50,350,250],[2,150,300,500],[3,50,400,200],[4,50,150,300],[5,450,350,150],[6,350,350,400],[7,200,100,150],[8,100,200,300]]$

a$.$

b$.$

c$.$ max$(A(3,$:$))$

d$.$

$2.$ Consider the following matrix of values:

$x=[14,23,54,112,80,334]$

Use a for loop to display how many values are greater than $23$ and less than $88?$

$3.$ Create MATLAB variables to represent the following matrices and use them in the following exercises.

$a=\left[\begin{array}{ccccc}81& 44& 5& 62& 103\end{array}\right],b=\left[\begin{array}{cccc}1& 13& 13& 19\\ 21& 7& 3& 40\\ 6& 34& 50& 120\end{array}\right],c=\left[\begin{array}{c}8\\ 10\\ 71\end{array}\right]$

i$.$ Assign to the variable $ml$ the first four values in matrix $a$ as the first row and all the values in matrix $b$ as the second, third and fourth row.

ii$.$ Assign to the variable $m2$ the values in matrix $c$ as the first column, the values in matrix $b$ as columns $2,3,4,$ and $5$ and the values in matrix $a$ as the last row.

iii. Find the the row and column numbers of the elements in matrix $m2$ that contain values less than $30.$

iv$.$ Find the values in matrix $m2$ that are greater than $50.$
