If for example, I have the letter 'a' in table punnettSquare(2,1) and I want to add a letter 'b' to that same cell so that the element of the cell would be 'ab'. What function should I use?

punnettSquare =

5×5 cell array

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{'a' } {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

I want to make punnettSquare to be

punnettSquare =

5×5 cell array

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{'ab' } {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
