may I suggest reinforcing your test suite using isequal or strcmp to hardcoded diamond strings?

its unclear what the problem wants plz fix

Needs better test suite rather than just checking random things (which is better suited to be the secondary fail safe not the primary).
This is just lazy from the OP.

why is the first test showing error while others passing :
assert(all(find(double(make_diamond(3)) == 0) == [1 3 5 7 9]') == 1)

Matrix dimensions must agree. Error in Test1 (line 4) assert(all(find(double(make_diamond(3)) == 0) == [1 3 5 7 9]') == 1)
what is this supposed to mean? Am I missing something?
