MATLAB Programming

Regular Expressions
Remove the grouping, and the {2,} now applies only to [aeiou]. The
command is entirely different now as it looks for a nonvowel followed by at
least two consecutive vowels:
expr = '[^aeiou][aeiou]{2,}';
[mat ix1 ix2] = regexp(pstr, expr, 'match', 'start', 'end')
mat =
'see'
ix1 =
18
ix2 =
20
Atomic Grouping — (?>expr)
Alternative Match — expr1|expr2
Use p 1
|p 2
to pick out words in the string that start with let or tel:
regexpi(pstr, '(let|tel)\w+', 'match')
ans =
'lets' 'telegram'
Nonmatching Operators
The comment operator enables you to insert commentsintoyourcodetomake
it more maintainable. The text of the comment is ignored by MATLAB when
matching against the input string.
Operator
(?#comment)
Usage
Insert a comment into the expression. Comments are
ignored in matching.
Including Comments — (?#expr)
Use (?#expr) to add a comment to this expression that matches capitalized
words in pstr. Comments are ignored in the process of finding a match:
