Write MATLAB code to create a 5x5 matrix A with 2's on the
diagonal, and -1 on the super- and sub-diagonal. Then replace the
(1,1) element of A with a 1.
(Make your commands capable of handling an arbitary sized NxN
matrix by first defining N=5, then using the variable N as the size
in each of the commands.)

Create the 10×10 elementary matrix E that would switch the rows
3 and 7. Do not enter the matrix manually, but use the command eye
to create the identity matrix and modify the appropriate entry.
For instance >> E(3,3)=0
with change the (3, 3) entry of E to 0.
Test your matrix with a random 10 × 10 matrix.

Part 2: Solve the following problems in
MATLAB
1. Fill in the function E = myElim(A, r_entry, r_pivot, c) to
create an m by m
elimination matrix ??. Remember that
an elimination matrix looks like an identity matrix with one extra
entry of ?? in row r_entry and column r_pivot.
2. Fill in the function M = myMult(A, c_pivot) to create an m by
m multiplier matrix ??. Remember that a multiplier matrix looks
like an identity matrix with the...

Consider the magic matrix:
A = np.array([[17, 24, 1, 8, 15],
[23,
5, 7, 14, 16],
[
4, 6, 13, 20, 22],
[10,
12, 19, 21, 3],
[11,
18, 25, 2, 9]])
The matrix A has 5 row sums (one for each row), 5 column
sums (one for each column) and two diagonal sums. These 12 sums
should all be exactly the same. Verify that they are the same by
printing them and “seeing” that they are the same.
