Unique data and shuffle data problem in matlab

I had array of data with repeated values...
So, had to get non-repetitive arrays.
This could be done by :
b = unique(data);

for more one can read help unique. This is very useful function.

Moreover, I had to shuffle the data so that they are not perfectly aligned:
I found the function shuffle:

function x = shuffle(x)

%SHUFFLE Shuffle an array of values.

% x = shuffle(x) shuffles the vector x in random order.

% Since this function changes the vector x,

% it creates a copy of it.

n = length(x);

disp n

for index = 1:n

% a random number between i and n

r = index + floor((n-index+1) * rand());

% swap elements index and r

x([index r]) = x([r index]);

end

Surprisingly, it worked for whole matrix.
