's' is a char array where "s" denotes a string.

[] is an empty array. You can find more info on <missing> here

For your first question, see the "Text in String and Character Arrays" Topic on this documentation page.

For the second, missing returns a scalar value (and so you can store it in an element of a normal array) while [] returns a 0-by-0 value (and so trying to include it in an array may fail because of size mismatches.)

x = [1 missing; 3 4] % works, result is 2-by-2

y = [1 []; 3 4] % fails because row 1 would have 1 element and row 2 would have 2 elements

Yes so they are stored as a cell array in those fields.
