strcmpi

Compare strings in Stateflow chart (case insensitive)

Since R2021b

Syntax

tf = strcmpi(str1,str2)

Description

tf = strcmpi(str1,str2) compares strings str1 and str2, ignoring differences in letter case. The operator returns 1 (true) if the strings are identical and 0 (false) otherwise.

Note

The operator strcmpi is not supported in Stateflow^® charts that use C as the action language.

Examples

Compare Strings While Ignoring Case

Set x to 0 (false) because the strings do not match. Set y to 1 (true) because the strings match when you ignore case.

str1 = "Hello, World!";
str2 = "hello, world!";
x = strcmp(str1,str2);
y = strcmpi(str1,str2);

Input Arguments

str1, str2 — Input strings

string scalar

Input strings, specified as string scalars. Enclose literal string with double quotes.

Example: "Hello"

Limitations

• This operator does not support the use of Stateflow structure fields or messages. For more information about structures in Stateflow, see Access Bus Signals.
