A character string is a sequence of any number of characters enclosed in single quotes. You can assign a string to a variable.
myText = 'Hello, world';
If the text includes a single quote, use two single quotes within the definition.
otherText = 'You''re right'
otherText = You're right
myText and otherText are arrays, like all MATLAB® variables. Their class or data type is char, which is short for character.
Name Size Bytes Class Attributes myText 1x12 24 char
You can concatenate strings with square brackets, just as you concatenate numeric arrays.
longText = [myText,' - ',otherText]
longText = Hello, world - You're right
To convert numeric values to strings, use functions, such as num2str or int2str.
f = 71; c = (f-32)/1.8; tempText = ['Temperature is ',num2str(c),'C']
tempText = Temperature is 21.6667C
