indStrSubset

Returns the indices corresponding to the location of the substring, if it is a subset of the other given string. (Deprecated: see str_index_of_substr.)

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"  ; This library is automatically loaded
                                                             ; from NCL V6.2.0 onward.
                                                             ; No need for user to explicitly load.

	function indStrSubset (
		str        [1] : string,  
		str_subset [1] : string   
	)

	return_val [*] :  integer

Arguments

Variable of type string which will be searched for a substring.

Variable of type string specifying the subset.

Description

Note: this function is potentially very slow and has been deprecated. str_index_of_substr should be used instead.

Return the indices where str_string is contained within the variable str.

The inputs, str and str_subset, are converted to characters. If str_subset is a subset, then the indices [subscripts] of the character sequence are returned. If str_subset is not a subset of str, then a integer missing value is returned.

Examples

Example 1

If the string "orange" is a subset of "apple_orange_banana", return the indices of chararacter locations.

   aop = "apple_orange_banana"   
   o   = "orange"               
   ii  = indStrSubset(aop, o ) 
   if (.not.any(ismissing(ii))) then  
       print(ii)
   end if
