Create a string array where every element is an empty string. You can preallocate a string array with
the strings function.
str = strings(2,3)
str = 2x3 string
""
""
""
""
""
""
To create a missing string, convert a missing value using the string function. The missing string
displays as .
str = string(missing)
str =

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
""
"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.
