strsect

Purpose

Extracts a substring of a string.

Format

y = strsect(str, start, len)
Parameters:
  • str (string or scalar) – data from which the string segment is to be obtained.
  • start (scalar) – the index of the substring in str. The index of the first character is 1.
  • len (scalar) – the length of the substring.
Returns:

y (string) – the extracted substring, or a null string if start is greater than the length of str.

Examples

// String to search in
strng = "This is an example string.";

// Remove section of string
y = strsect(strng, 12, 7);

The above code assigns the variable y to be:

Remarks

If there are not enough characters in a string for the defined substring to be extracted, then a short string or a null string will be returned.

If str is a matrix containing character data, it must be scalar.
