MENG-201
1) Write a script that receives a random positive integer number ? and prints the
matrix ? , which is a diagonal ? × ? matrix, with the following pattern:
Example: ? = 2 ? ? = ?
?2 + 1 0
0 ?3 + 2
?
? = 3 ? ? = ?
?2 + 1 0 0
0 ?3 + 2 0
0 0 ?4 + 3
?
? = 4 ? ? =
?2 + 1 0 0 0
0 ?3 + 2 0 0
0
0
0
0
?4 + 3
0
0
?5 + 4
2) Write a script that receives a random row matrix called A, if the number of elements
of the matrix is even (1 × 2? matrix) it picks elements in pairs and divides the evenly
placed element of a pair by the oddly placed element of that pair, and prints the
answers in a 1 × ? matrix called B, and if the number of the elements in the received
matrix is odd, it should print the error message as: “This operation is not possible!”
Example: A=[1, 4, 7]
Output: “The operation is not possible”
A=[1, 4, 7, 17.5, -2, 14]
Output: B=[
4
1 ,
17.5
7 ,
14
-2
]
A=[-18 ,5.5 , 3.12 , 17.8 ,16 , -1, 12 ,12]
Output: B=[
5.5
-18 ,
17.8
3.12 ,
-1
16 ,
12
12]
Note: For simplicity assume the oddly placed elements cannot be zero
3) Write down the script for plotting the function ? = 6 ln(?) – 7?-0.2? over the
interval 1 = ? = 3 , and then label the axis accordingly. Suppose ? is representing the
velocity of a cart with respect to time.
4) Write a script that receives a random ? × ? matrix, and creates a new row matrix that
lists all the even elements of the input (assume your input has at least one even value)
