Finding the indexes of a classified data from another classified data

 

findcl	Find the indexes of a classified data from another classified data
-c1 <cldata1>	classified data for classes
-c2 <cldata2>	classified data to be mapped
-cout <cldata>	resulting classified data
[-first]	locate only the first matching index

This operation matches the indexes of classified data <cldata2> to the indexes of classified data <cldata1>, and replaces indexes in <cldata2> with the indexes of that class of <cldata1>, from which the first occurrence or all occurences are found. The whole procedure is presented below, and a step for matching one index is described as a figure:

 
For each   

		 For each class   

		 		 For each   

		 		 		 If    Then

		 		 		 		 Add i to    in the target classified data

		 		 		 		 Continue with next    if -first specified

		 		 		 EndIf

		 		 End

		 End

End
