Hi,
In the attached array sz, I need to delete every alternate rows starting from first row, (e.g. 1, 3, 5, 7 etc). Could someone help?

You have been active here since 2020, I am really surprised that you had to ask for this.

Hi,
You can do
sz_new = sz(2:2:end, :);
This will do the job.

Ran in:
Alternatively you can also delete them from your current variable:
x = 1:10;
x % show x
x = 1x10
1 2 3 4 5 6 7 8 9 10
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
x(1:2:end) = [];% delete odd idx values
x % show x after removing odd values
x = 1x5
2 4 6 8 10
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
