For example, parse different parts of street addresses from several character vectors. A
short name is assigned to each token in the expression:

chr1 = '134 Main Street, Boulder, CO, 14923';
chr2 = '26 Walnut Road, Topeka, KA, 25384';
chr3 = '847 Industrial Drive, Elizabeth, NJ, 73548';

p1 = '(?\d+\s\S+\s(Road|Street|Avenue|Drive))';
p2 = '(?[A-Z][a-z]+)';
p3 = '(?[A-Z]{2})';
p4 = '(?\d{5})';

expr = [p1 ', ' p2 ', ' p3 ', ' p4];

As the following results demonstrate, you can make your output easier to work with by
using named tokens:

loc1 = regexp(chr1, expr, 'names')

loc1 =

struct with fields:

adrs: '134 Main Street'
city: 'Boulder'
state: 'CO'
zip: '14923'

loc2 = regexp(chr2, expr, 'names')

loc2 =

struct with fields:

adrs: '26 Walnut Road'
city: 'Topeka'
state: 'KA'
zip: '25384'

loc3 = regexp(chr3, expr, 'names')

loc3 =

struct with fields:
