Strings as Vectors:

The Strings are considered as vectors of characters-or in another words, a vector in which each and every element is a single character-so numerous vector operations can be performed. For illustration, the number of characters in a string can be found by using the length function:

 

>> length('cat')

ans =

3        

>> length(' ')

ans =

1

>> length('')

ans =

0

 

Notice that there is a distinction between an empty string, that has a length of zero, and a string consisting of a blank space, that has a length of one.

The Expressions can refer to a separate element, or a subset of a string or a transpose of the string:

>> mystr = 'Hi';

>> mystr(1)

ans =

H

>> mystr'

ans =

H

i

>> sent = 'Hello there';

>> length(sent)

ans =

11

>> sent(4:8)

ans =

lo th

 

Note that the blank space in the string is a valid character contained by the string.
