strmatch¶
strmatch checks if elements of a string matrix match a pattern.
-
rmBool = strmatch(ssPattern, smString)
Return Value
rmBool is real matrix. A matrix element of rmBool is True (1), if the corresponding string element of smString matches the pattern ssPattern, and False (0), if the corresponding element of smString does not match the pattern.
Parameters
-
ssPattern ssPattern is a scalar string containing a pattern.
| Value | Meaning |
|---|---|
| * | Match zero or more characters. |
| ? | Match any single character. |
| [SET] | Matches any character in the specified set. |
| [!SET] or [^SET] | Matches any character not in the specified set. For example, the pattern [aAbB] or [0-9A-Z] will match the numbers 0 to 9 and all upper case alphabetic characters. If any of the characters []*?!^-are used in [SET], a double backslash “" |
-
smString smString is a string matrix.
Comment
A set is composed of characters or ranges; a range looks like
character hyphen character (as in 0-9 or A-Z). [0-9a-zA-Z_] is the
minimal set of characters allowed in the [..] pattern construct.
To suppress the special syntactic significance of any of []*?!^-\,
and match the character exactly, precede it with a \\.
Example
The following example shows how to find out if a string contains small letters.
* strmatch("*[a-z]*", ["Hallo", "HALLO"])
1.0000 0.0000
Example
* strmatch("hello", "hello")
1.0000
* strmatch("hello", "Hello")
0.0000
* strmatch("[hH]ello", "Hello")
1.0000
* strmatch("*ello", "Hello")
1.0000
* strmatch("*el?o", "Hello")
1.0000
* what("strm*")
