Hello ,
I need help in matlab , this sounds easy but i can not seem to find a solution , here is an example :
data = [1 0.1
2 0.2
3 0.3
4 0.4
5 0.5
6 0.6 ]
i want to shuffle the test data , i mean the first line become the third line and the third line becoms the forth line for examle , but the order in the line remaind the same
Here is an example of how i want the data to become :
data = [1 0.1
6 0.6
2 0.2
5 0.5
4 0.4
3 0.3 ]
is there a matlab function that allows me to do that , and thanks in advance .

"he first line become the third line and the third line becoms the forth line"
your example doesn't meet what you described.
I guess you want do a random shuffling of data by rows.
newData = data(randperm(6), :)
newData =
4.0000 0.4000
1.0000 0.1000
6.0000 0.6000
5.0000 0.5000
2.0000 0.2000
3.0000 0.3000
