feature to record your work. Include your written conclusions in your diary ﬁle as
well.
When ﬁnished, print out your diary ﬁle and submit it with the rest of your assignment.
Determinants
To ﬁnd the determinant of a matrix in MATLAB, use the
det
command.
For example, the determinant of the matrix
A
=
1 2 3
4 5 6
7 8 0
can be found as follows:
>> A = [1 2 3; 4 5 6; 7 8 0]
>> det(A)
MATLAB returns that the determinant of
A
is 27.
Question 1
(a) Construct a random 5x5 matrix,
A
, with integer entries between 9 and 9 (see MATLAB’s
randint
command). Compare
det
(
A
) with
det
(
A
T
),
det
(

A
),
det
(2
A
), and
det
(10
A
).
(b) Repeat part (a) with a random 6x6 matrix,
