The root cause of the error is that the indexing of the 'assignments' array is not 'fixed'. A requirement of sliced variables in parfor-loops is that the indexing expression must be the same for all occurrences. A few different approaches could solve the issue of different indexing expressions,e.g.,
trackIdx = assignments(i, 1);
detectionIdx = assignments(i, 2);
1. Split the 'assignments' array into two different arrays.
2. Reorganize the 'assignments' array into a cell array of pairs, e.g., trackIdx = assignments{i}(1), detectionIdx = assignments{i}(2)
3. Add a nested for-loop with an if-else statement.
for j=1:2
if mod(j,2) == 1
trackIdx = assignments(i,j)
else
detectionIdx = assignments(i,j)
end
