[0 0 0;1 2 3] is an example of a matrix i Matlab. Please try the rest yourself. We are not here to do your homework. If you gave it a try, and fail, then come with specific questions what you dont understand.

Use sqrt() for square root, pi for pi, commas between columns, and semicolons between rows. For example
m = [0, 1, pi;
sqrt(2), 2, 0]
m =
0 1 3.1416
1.4142 2 0

clc; clear all;

A = 5×5

Unfortunately now she'll have to come up with a different way to do this
because you gave a complete solution, unlike the other answers that just gave hints. Some universities employ plagiarism detectors, which scan the web for similar code, meaning she can't submit your solution as her own or else she'll get caught cheating. However, she might be okay because there are a very limited number of ways to make this matrix so it's possible students could have thought of it on their own, even if you hadn't posted the answer.

Please don't do homework assignments for people. That does not help them, except to learn there is sometimes someone out there who is foolish enough and willing to do their work for them.
