Test Suite

Test Status Code Input and Output
1   Fail
strs = {'aa','bb','aa','aa'}; correct = {'aa'}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

The logical indices in position 1 contain a true value outside of the array bounds. Error in duplicates (line 12) strs(idxkeep,:) Error in Test1 (line 3) result = duplicates(strs);

2   Fail
strs = {'10','11','12'}; correct = {}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

The logical indices in position 1 contain a true value outside of the array bounds. Error in duplicates (line 12) strs(idxkeep,:) Error in Test2 (line 3) result = duplicates(strs);

3   Fail
strs = {'zzz','zzz','zzz'}; correct = {'zzz'}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

The logical indices in position 1 contain a true value outside of the array bounds. Error in duplicates (line 12) strs(idxkeep,:) Error in Test3 (line 3) result = duplicates(strs);

4   Fail
strs = {'a','b','c','b','d','c'}; correct = {'b','c'}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

The logical indices in position 1 contain a true value outside of the array bounds. Error in duplicates (line 12) strs(idxkeep,:) Error in Test4 (line 3) result = duplicates(strs);

5   Fail
strs = {}; correct = {}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

Error using histcounts Expected input number 2, m, to be positive. Error in histcounts (line 139) validateattributes(in,{'numeric','logical'},{'integer', 'positive'}, ... Error in duplicates (line 6) [count, ~, idxcount] = histcounts(idxc,numel(idxu)); Error in Test5 (line 3) result = duplicates(strs);
