![Matrix addition and subtraction (p. 121-122)
We can use the numpy. add and numpy. subtract functions to add and subtract
atrices in Python as in the following code, which follows from the preceding code:
#Add A and B
print (numpy. add (A, B) )
# Subtract A and B
print (numpy.subtract (A,B))

The code has the following output:
[[ 4 3 3]
[17
4 2]
[ 3
4 4]]
[[ 2
1 -1]
[ 1 -4 0]
[ 3 4 -2]]
Of course, this is in fact A + B and A- B, which we could find by hand if we add and
subtract all the numbers in the matrices element by element.
Next, we continue with more arithmetic of matrices: multiplying a whole matrix by
a scalar (or, by a number).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faeb82f7c-4539-4167-ae2c-8d769f758121%2Fcf855194-83fa-462b-bc63-21e3ec39698d%2Ffc45gv_processed.jpeg&w=3840&q=75)

Transcribed Image Text:Perform the following tutorial-style labs, taken from our supplementary textbook,
using the programming language python. You do not need to have python on your
computer. Please use the following online editor and interpreter:
https://www.online-python.com/
Just enter the code as shown, run, and view the results. In addition, you will be
given one exercise of your own to do, based directly on the given examples (thus
little to no original programming is required to do the exercise). These labs are not
intended to be python programming labs - you do not need to have prior
knowledge of python, although some prior knowledge of C-style language may be
helpful. The point is to gain some experience using linear algebra to solve
problems on your computer, not to teach computer programming. Any
modifications to the code you are given will be minor, and should not cause any
problems for someone with a background in C.
Please take screenshots of all your resulting output, on your screen as it appears in
the above online interpreter. Submit these screenshots and your code on
Blackboard. Also answer any additional problems you are given.
