Hi everyone, I have z
z = [1 1 0 0;
1 0 1 0;
1 0 0 1;
0 1 1 0;
0 1 0 1;
0 0 1 1;]
each of z's row are states that I want my code to go through one by one (from 1 1 0 0 to 0 0 1 1) , and after each state is run, it produces w. after running all the 6 states from z,
w = [a;
a;
a;
a;
a;
a;];
Is there a code where I can run each state of z in a loop, and produces w?

"a" is calculated number. Meaning, for each time it loop, "a" is generated until the loop finishes.

This code will loop over each row of Z and put the results into w. I'm not sure what you want to do with each row.
z = [1 1 0 0;
1 0 1 0;
1 0 0 1;
0 1 1 0;
0 1 0 1;
0 0 1 1;]
numRows = size(z,1); % counts the number of rows
w = nan(numRows,1); % preallocate w;
for ii = 1:numRows
thisRow = z(ii,:);
% do something here to get a?
a=sum(thisRow);
w(ii) = a;
end

Yes, I put it up as anothe question
