Note

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

Examples

newStr = strrep(str,"world","Mars");

Stateflow chart that uses the strrep operator in a state.

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.

Algorithms

The strrep operator replaces overlapping substrings. For example, strrep("abc 2 def 22 ghi 222 jkl 2222","22","*") returns "abc 2 def * ghi ** jkl ***". To replace only sequential substrings, use replace. For more information, see Replace Repeated Pattern.
