This searches for a value associated with a given key. If an exact match is not found, the result will depend on how the input port “Value If Not Found” is defined. If a default value is defined by this port, that value will be returned. Otherwise, the execution will an error and the model execution will be interrupted.
It is also possible to search for an approximate match using a Calculate Value, Calculate Map, Calculate Categorical Map or Calculate Lookup Table. See the “Lookup Table Operators” description on the Image Expression Type documentation.
