1×1 cell array

You can also search for the email address of everyone in the list by using the entire cell

array for the input argument:

regexp(contacts, email, 'match');

Operators and Characters

Regular expressions can contain characters, metacharacters, operators, tokens, and flags

that specify patterns to match, as described in these sections:

• “Metacharacters” on page 2-46


• “Character Representation” on page 2-48


• “Quantifiers” on page 2-48


• “Grouping Operators” on page 2-49


• “Anchors” on page 2-50


• “Lookaround Assertions” on page 2-51


• “Logical and Conditional Operators” on page 2-52


• “Token Operators” on page 2-52


• “Dynamic Expressions” on page 2-54


• “Comments” on page 2-55


• “Search Flags” on page 2-55

Metacharacters

Metacharacters represent letters, letter ranges, digits, and space characters. Use them to

construct a generalized pattern of characters.
