Hi
I have a text file with a big matrix. I want to select all the even rows and export to a new text file, and then select all the odd rows to another new text file.
For example, I have a A.txt with a matrix like below
1 1 1 …
2 2 2…
3 3 3 …
4 4 4 …
…
I want to separate them into to two new text files, as shown below
B.txt
1 1 1 …
3 3 3 …
…
C.txt
2 2 2 …
4 4 4 …
…
Thank you so much.

X = X(1:2:end,:); %keep odd rows
X = X(2:2:end,:); %keep even rows
