The Search 1D Array function returns the index of the first occurrence of an element in a one-dimensional array or -1 if no match is found. Search starts at the specified start index or at index zero if no start index is specified.
Usage
Connect a one-dimensional array to the 1D array terminal and the element to find at element. The function returns the index of the first matching element.
To find an element after the first match, set start index to a value higher than the previous match.
If no match is found the return value is -1
Best practice
- Use Reverse 1D Array to search elements from end to start.
- Be careful when using this function on non-integer values[1][2].
