need to skip iterations in a for loop

I'm trying to set values in a row of a large 2D matrix to 1, but i need to skip every two entries, so have my last row look something like 1001001001 instead of my current L(bottomrow,:)=1. I was thinking about using a for loop but i'm not so sure how to set that up, I tried

L=zeros(1024,1024);

for n=(2:1022:3)

L(1024,n)=1

end

using n from 2 to 1022 because i'm using dummy arrays for my code.

L=zeros(1024,1024);
% for n=(2:1022:3)
%     L(1024,n)=1
% end 

% Set the last row (first end), column 2 to last column with a step 3 to be
% 1 (you can adjust this for your need)
L(end, 2:3:end) = 1;

L(end, :)

ans = 1×1024

0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0
