define "higher up", is row 1 higher or lower than row 4?
Don't test with with 2 or more straight flushes with different rankings.
@Jean,
Huh? Is that a suggestion to add a test?
Yes, as for example test 8 in problem 333 : Poker Series 02: isQuads.
It is better to modify the last test case as hm = [0 0 0 0 0 0 0 0 1 1 0 1 1;
1 1 0 0 0 0 0 0 0 1 1 1 1;
1 0 0 0 0 0 0 0 0 1 1 1 1;
0 0 0 0 0 0 0 0 0 0 0 0 0];
y_correct.flag = true;
y_correct.usedCards = logical([0 0 0 0 0 0 0 0 0 0 0 0 0;
1 0 0 0 0 0 0 0 0 1 1 1 1;
0 0 0 0 0 0 0 0 0 0 0 0 0;
0 0 0 0 0 0 0 0 0 0 0 0 0]), where I have interchanged the 2nd and 3rd rows of hm. The reason to make this change is that some solutions which simply check whether the row sum equals 5 are indeed incorrect.
Very late here since the last comment, but if you care to update, my code passed all the tests but it ran into an error when dealing with a normal flush. May want to put a test in there for five 1's in a single row but not consecutive
So, just to clarify, because in normal poker, 9 10 J Q K beats A 2 3 4 5, at least I think and an online simulator proved that to be correct...
in your case, A high beats K high? I might need to analyze the expected answers a bit but you did say in your problem statement that A high trumps, so I just wanted to check
If you are starting the Poker Series, consider including a score for the hand in your code. Problems 19 will allow you to identify the hand types (flush, straight, quads, etc.) in problem 10, but in problem 11 you will need a way to break ties between two straights, two full houses, two flushes, etc. For this problem, for example, the score could simply be the high card of the straight flush.

Is there a problem with the third test? Looks like a fourth test was being created. I think my solution should pass.

The second part of Test 3 looks incorrect. This problem has two straight flushes on rows 2 & 3. However, the expected solution only shows a straight flush on row 2
hm = [0 0 0 0 0 0 0 0 1 1 0 1 1
1 0 0 0 0 0 0 0 0 1 1 1 1
1 1 0 0 0 0 0 0 0 1 1 1 1
0 0 0 0 0 0 0 0 0 0 0 0 0];
y_correct.flag = true;
y_correct.usedCards = logical([0 0 0 0 0 0 0 0 0 0 0 0 0
1 0 0 0 0 0 0 0 0 1 1 1 1
0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0])
assert(isequal(isStraightFlush(hm),y_correct))

This should satisfy the second part.. I think.

This should only satisfy the first part.
