Represent Text with String Arrays
You also can store text in string arrays. Each element of a string array stores a 1-by-n
character vector.
Starting in R2017a, you can create strings using double quotes. MATLAB® displays
strings with double quotes.
str = "Welcome, friend"
str =
"Welcome, friend"
As an alternative, you can convert a character vector to a string using the string
function.
chr = 'Hello, world';
str = string(chr)
str =
"Hello, world"
str is a 1-by-1 string, or string scalar. To find the number of characters in a string, use
the strlength function.
whos str
Name Size Bytes Class Attributes
str 1x1 174 string
strlength(str)
ans = 12
You can store multiple pieces of text in a string array. Each element of the array can
contain a string of a different size.
str = ["Mercury","Gemini","Apollo";...
"Skylab","Skylab B","ISS"]
str = 2x3 string array
"Mercury" "Gemini" "Apollo"
"Skylab" "Skylab B" "ISS"
