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.


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.

  • Use Reverse 1D Array to search elements from end to start.
  • Be careful when using this function on non-integer values[1][2].
