MATLAB Programming

Regular Expressions
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(str1, expr, 'names')
loc1 =
adrs: '134 Main Street'
city: 'Boulder'
state: 'CO'
zip: '14923'
loc2 = regexp(str2, expr, 'names')
loc2 =
adrs: '26 Walnut Road'
city: 'Topeka'
state: 'KA'
zip: '25384'
loc3 = regexp(str3, expr, 'names')
loc3 =
adrs: '847 Industrial Drive'
city: 'Elizabeth'
state: 'NJ'
zip: '73548'
Conditional Expressions
With conditional expressions, you can tell MATLAB to match an expression
only if a certain condition is true. A conditional expression is similar to an
if-then or an if-then-else clause in programming. MATLAB first tests the
state of a given condition, and the outcome of this tests determines what, if
anything, is to be matched next. The following table shows the two conditional
syntaxes you can use with MATLAB.
