You can create a string array with both empty and missing strings. Use the ismissing
function to determine which elements are strings with missing values. Note that the
empty string is not a missing string.
str(1) = "";
str(2) = "Gemini";
str(3) = string(missing)
str = 1x3 string array
"" "Gemini"
ismissing(str)
ans = 1x3 logical array
0 0 1
Compare a missing string to another string. The result is always 0 (false), even when
you compare a missing string to another missing string.
str = string(missing);
str == "Gemini"
ans = logical
0
str == string(missing)
ans = logical
0
Access Elements of String Array
String arrays support array operations such as indexing and reshaping. Use array
indexing to access the first row of str and all the columns.
str = ["Mercury","Gemini","Apollo";
"Skylab","Skylab B","ISS"];
str(1,:)
