Split a data in random partitions

Hi,

I'm trying to split my data in random partition.

I have a code of this type :

rng(1000)

cv = cvpartition(size(my_data,1),'HoldOut',0.4);

idx = cv.test;

dataTrain = split(~idx,:);

dataTest = split (idx,:);

The problem is that it provides me dataTrain as a (0x12)table instead of (1200x12)table.

How can I fix this problem ?

A = rand(100,2) ; 

n = size(A,1) ; 

% Get 70% of data random from A
m = round(0.7*n) ; 
% Randomize the data
idx = randperm(n) ;
% Training data 
P = A(idx(1:m),:) ; 
% Testing 
T = A(idx(m+1:end),:) ;
