extractAfter

Extract substring after position

Since R2021b

Syntax

newStr = extractAfter(str,subStr)

newStr = extractAfter(str,pos)

Description

newStr = extractAfter(str,subStr) returns the substring of str that begins after the last occurrence of the substring subStr.

newStr = extractAfter(str,pos) returns the substring of str that begins after the character position pos.

Note

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