Sort random number at a matrix

Dear community,

I would like to sort a matrix size (4998x2) on random form.

The follow code it was used:

n=4998
Matrixw = repmat(x, 1, ceil(n/numel(x)));
Matrixw = Matrixw(randperm(n));

The head of data is: 
TT	Test1
TT	Test2
TT	Test3
TT	Test4
CN	Test5
CN	Test6
CN	Test7
CN	Test8
CN	Test9
CN	Test10
SN	Test11
SN	Test12
SN	Test13
SN	Test14
SN	Test15
SN	Test16
SN	Test17

Using the code above, just first column is random sort, but, I need that respectivly both column of the matrix are random sort, in the other words:

SN Test17

TT Test4

CN Test7

Each pair of variable is random sort, but together.

Can help me, please?

Yours faithfully

% a matrix
M = reshape(1:100,[],2)

M = 50×2

1 51 2 52 3 53 4 54 5 55 6 56 7 57 8 58 9 59 10 60

% randomly reorder the rows
M = M(randperm(size(M,1)),:)

M = 50×2

3 53 33 83 31 81 42 92 18 68 27 77 37 87 29 79 24 74 16 66

Do you mean like this -

n = 10;

x = [(1:10)' (10:-1:1)']

x = 10×2

1 10 2 9 3 8 4 7 5 6 6 5 7 4 8 3 9 2 10 1

idx = randperm(n)

idx = 1×10

1 6 3 5 4 9 8 10 2 7

x = x(idx,:)

x = 10×2

1 10 6 5 3 8 5 6 4 7 9 2 8 3 10 1 2 9 7 4
