Compare two input strings
Libraries:

Description
String Compare compares two strings. To see if two strings are identical, use this block. You can specify if the match is case sensitive and how much of the string to compare.
Ports
Input
First string to compare, specified as a scalar.
Data Types: string
Second string to compare, specified as a scalar.
Data Types: string
Output
True or false result, specified as a scalar:
1— Match.0— No match.
Data Types: Boolean
Parameters
Case sensitivity for string comparison:
on
Consider string case when comparing strings.
off
Do not consider string case when comparing strings.
Programmatic Use
| Block Parameter: CaseSensitive |
|---|
| Type: character vector |
| Values: 'on' | 'off' |
| Default: 'on' |
Amount of string to compare:
Entire string— Compare both entire strings.First N characters— Compare the first_N_ characters of both strings.
Dependencies
Setting this parameter to First N characters enables the Number of characters parameter.
Programmatic Use
| Block Parameter: CompareOption |
|---|
| Type: character vector |
| Values: 'Entire string' | 'First N characters' |
| Default: 'Entire string' |
Number of characters to compare
Dependencies
This parameter is enabled when the Compare Option parameter is set to First N characters.
Programmatic Use
| Block Parameter: CompareOption |
|---|
| Type: character vector |
| Values: scalar |
| Default: '1' |
