The class() function can reveal what type of data is being input. To sort it you could check the class of the input and store it in a vector. This code is assuming your "input" is from an outside source so this is treated like a separate function call. If the input is internal then you could also use a for-loop around the switch-case
global array8 array16 array32
input = uint8(12);
switch class(input)
case 'uint8'
array8(end+1) = input;
case 'uint16'
array16(end+1) = input;
etc.
that's just a demo, you'd have to include
array8 = []
and stuff for that to be functional. If you're more specific we could help you out a bit better, but that should get you started :)
