Perhaps a better strategy is to make a new problem instead of frequently re-scoring due to incremental changes. BTW, the newly added last test case (#11) should return 2, not 1.
Yes, Test 11 -> 2
Test case 11 is still incorrect.
x = [i -2 -4i 8 16i] is an arithmetic serie ?
Test case 11 fixed. Thanks.
Your "if ..." returns false positive on complex input.
This solution will fail a test with x = [1 1 -1 -1]; y_correct = 0; assert(isequal(stype(x),y_correct)); Thus, I recommend to reinforce the test suite by adding this test.
Indeed. Test added. Thanks!
