MAE 107
Problem JDGNA01
1.) In the Matlab command window, construct an
m
×
n
matrix
A
= [
A
ij
], say, A, in Matlab notation, with
m,n
each being approximately three or four and not necessarily equal, and
A
ij
being real numbers of
your choosing. Then. verify by inspection that the jth column vector
c
j
of
A
is produced by a Matlab
command of the form A(:, j). What is the command for generating the row vectors
r
T
of
A
?
For the special case:
A
=

hand in a diary ﬁle showing the single command line that achieves each of the following tasks:
a.) construction of
A
,
b.) extraction of its 3rd row,
c.) extraction of its 2nd column
2.) Verify that the Mfunction (Matlab function)
eye(n)
generates the
nxn
identity matrix (or ”idem
factor”) I
. Familiarize yourself also with the Mfunction
eye(k, j)
. Note that the rows and columns
of I
deﬁne, respectively, the canonical column basis
