extractAfter

Extract substring after position in Stateflow chart

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 first occurrence of the substring subStr. If subStr occurs multiple times in str, then newStr is str from the first occurrence of subStr to the end.

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.

Examples

Extract Text After Substring

Extract substring "world!" from a longer string.

str = "Hello, world!";
newStr = extractAfter(str,"Hello, ");

Extract Text After Position

Extract substring "world!" from a longer string.

str = "Hello, world!";
newStr = extractAfter(str,7);
