Can you explain your conditions in more detail. In particular, give several examples of specific numbers that match and do not match your criteria?

[First, Second, Third] = ndgrid(0:9);
First = First(:); Second = Second(:); Third = Third(:);
First == 9 || Second == 9 || Third == 9 | ((First == 4 || Second == 4 || Third == 4) & (First == 3 || Second == 3 || Third == 3)) ....
