1.1
Create a 2D numpy array given below using the builin numpy functions.
XXXXXXXXXX XXXXXXXXXX
25 −3 −3 −3 −3 −3 −3 −3 −3 25
25 − XXXXXXXXXX −9 6 −3 25
25 −3 0 0 0 −9 0 6 −3 25
25 −3 0 0 −9 0 0 6 −3 25
25 −3 0 − XXXXXXXXXX −3 25
25 −3 − XXXXXXXXXX −3 25
25 −3 −3 −3 −3 −3 −3 −3 −3 25
XXXXXXXXXX XXXXXXXXXX
1.2
Perform matrix multiplication between the following matrices below using numpy
builtin functions. Print out the resultant matrix along with its shape.
16 5
5 3
−3 19
7 17
XXXXXXXXXX1
5 5 − XXXXXXXXXX
1.3
Write a NumPy program to create a 3x3x3 array filled with random integer values.
Replace the middle layer with all ones using the np.ones function
2 -Topic Name2.1
Create a random 5x5 numpy array composed on integers (range 0-100), and then
calculate its determinant. Sort this array using the np.sort() function.

2.2
Crete a 10x10 random integer numpy array (range 0-100).
• Using loops find the biggest entry in this numpy array
• Now use the builtin function to find the biggest entry
2.3
Write a program that finds the square and cube of all numbers from 0 to 100,
• First use loops to do this
• Now do the same thing using numpy arrays
