Hello red,
In a 'parfor' loop, temporary variables are cleared at the beginning of each iteration.
In your code, the variable 'U' is cleared at the start of each iteration, leading to issues. To resolve this, ensure that 'U' is initialized before it is used.
Refer to the following code for guidance:
parfor kk = 1:r
u = length(YY{i}(kk, :));
uu = YY{i}(kk, :);
Find1 = [uu(1:u-1); uu(2:u)];
Find1 = Find1';
[C, ia, ib] = intersect(Arc, Find1, 'rows');
U = zeros(1, length(Arc)); % Initialize U here
U(ia) = 1;
HH = [HH; U];
hh = [hh; length(Find1) - 1];
end
For more information, please refer to the documentation on Temporary variables in 'parfor':
