given a number, find all the fangs of that number.

A pseudo-vampire number can have multiple of fangs. The output should be a cell containing all the pairs of possible fangs.

For example, 126 is a pseudo-vampire number whose fangs are - { '6' , '21' }

126 = 6*21
6 and 21 contains the digits of the original number.

The required output format is inconvenient.
1. The order of tuples and the order within the tuples should not matter.
2. Why not simply a cell array of vectors (instead of cell array of cell array of char arrays or a single cell array of char arrays)?
