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.

example

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

example

Note

The matches operator is not supported in Stateflow® charts that use C as the action language. For similar functionality, use strcmp.

Examples

Return a value of 0 (false) because the strings do not match.

str2 = "hello, World!";
x = matches(str1,str2);

Return a value of 1 (true) because the strings match when you ignore case.

str1 = "Hello, world!";
str2 = "hello, World!";
x = matches(str1,str2,IgnoreCase=true);
