### 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 in solution Line: 2 Column: 7 The expression to the left of the equals sign is not a valid target for an assignment.

2   Fail

Error in solution Line: 2 Column: 7 The expression to the left of the equals sign is not a valid target for an assignment.

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

Error in solution Line: 2 Column: 7 The expression to the left of the equals sign is not a valid target for an assignment.

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.
