Another important way to manipulate arrays is to sort their elements. As an
example we can use
sort(C,dim,mode)
with
dim=1
and
mode='ascend'
to sort
the elements of
C
in ascending order along the i rst array dimension (i.e., the
rows). Typing
I = sort(C,1,'ascend')
yields
I =
1 3 -1
2 4 3
6 6 3
9 9 3
h e function
sortrows(C,column)
with
column=2
sorts the rows of
C
according
to the second column. Typing
J = sortrows(C,2)
yields
J =
9 3 -1
2 4 3
6 6 3
1 9 3
Array manipulation also includes the comparison of arrays, for example
by checking whether elements in
A(i,j)
are also found in
B
using
ismember
.
Typing
A, B
K = ismember(A,B)
yields
A =
2 4 3
9 3 -1
B =
1 9 3
6 6 3
