matches

Determine if two strings match in Requirements Table block

Since R2022b

Syntax

tf = matches(str1,str2)

tf = matches(str1,str2,IgnoreCase=true)

Description

tf = matches(str1,str2) compares the strings str1 and str2. The operator returns 1 (true) if the strings are identical, and returns 0 (false) otherwise. Use this operator in the Requirements Table block.

tf = matches(str1,str2,IgnoreCase=true) compares strings str1 and str2, ignoring any differences in letter case.

Examples

Compare Strings

In a Requirements Table block, create a requirement that checks if the string "Hello, world!" matches the string "Hello, world!".

y = matches("Hello, world!","Hello, world!")

Compare Strings While Ignoring Case

In a Requirements Table block, create a requirement that checks if the string "Hello, world!" matches the string "hello, World!" regardless of case.

y = matches("Hello, world!","hello, World!",IgnoreCase=true)
