- IndexOf[ <Object>, <List> ]
- Returns position of first occurrence of Object in List, e.g.
IndexOf[5, {1, 3, 5, 2, 5, 4}]
returns 3. When the object is not found, result is undefined. - IndexOf[ <Object>, <List>, <Start Index> ]
- Same as above, but the search starts at given index.
Examples:
IndexOf[5, {1, 3, 5, 2, 5, 4}, 3]
returns 3.IndexOf[5, {1, 3, 5, 2, 5, 4}, 4]
returns 5.IndexOf[5, {1, 3, 5, 2, 5, 4}, 6]
returns undefined.
- IndexOf[ <Text Needle>, <Text Haystack>]
- Returns position of first occurrence of Needle in Haystack, e.g.
IndexOf["Ge", "GeoGebra"]
returns 1. - IndexOf[ <Text Needle>, <Text Haystack>, <Start Index> ]
- Same as above, but the search starts at given index.
Example:
IndexOf["Ge", "GeoGebra",2]
