### Test Suite

Test Status Code Input and Output
1   Fail
%% A = [2 2 2 3 3 2 3 8 6 5 6]; [U, H] = hunique(A); U_ok = [2 3 8 6 5]; H_ok = [4 3 1 2 1]; assert(isequal(U,U_ok)); assert(isequal(H,H_ok));

Error: Edge vector must be monotonically non-decreasing.

2   Fail
%% A = [2 2 2 3 3 2 3 8 6 5 6 8]; [U, H] = hunique(A); U_ok = [2 3 8 6 5]; H_ok = [4 3 2 2 1]; assert(isequal(U,U_ok)); assert(isequal(H,H_ok));

Error: Edge vector must be monotonically non-decreasing.

3   Fail
%% A = 100:-11:1; assert(isequal(hunique(A),A)); [~,H] = hunique(A); assert(isequal(H,ones(1,10)));

Error: Edge vector must be monotonically non-decreasing.

4   Fail
%% A = randi([-10 10],1,100); [U,H] = hunique(A); assert(sum(H)==numel(A)); assert(isequal(unique(A),sort(U))); % number of test cases may increace in the future. % any proposals of test cases warmly welcome.

Error: Edge vector must be monotonically non-decreasing.
