num2cellstr

is there a function that converts an array of numbers to a cell array
of strings?
num2cell converts array of numbers -> cell array of numbers
num2str converts array of numbers -> char array (but not cell array)

I suppose I can do this easily, it just seems like an obvious idea for
a builtin function

No.

cellfun(@num2str,num2cell(TheMatrix),'Uniform',0)

AFAIK there is no single function that can do this but as you said
it's easy enough to create your own:

>> data =3D num2cell([1:5]);
>> data =3D cellfun(@num2str,data,'UniformOutput',false)

data =3D

'1' '2' '3' '4' '5'

HTH,

what about:

data = rand(3,4)
CS = reshape(cellstr(num2str(A(:))),size(A))
