Inner join between two tables or two timetables

creates
the table or timetable, `C`

= innerjoin(`A,B`

)`C`

, as the inner join between `A`

and `B`

by
matching up rows using all the variables with the same name as key variables. `A`

and `B`

are
both tables or both timetables. You cannot perform an inner join between
a timetable and a table.

The inner join retains only the rows that match between `A`

and `B`

with
respect to the key variables. `C`

contains all nonkey
variables from `A`

and `B`

.

If `A`

and `B`

are timetables,
then the key variables are the vectors of row times of `A`

and `B`

.

performs
the inner-join operation with additional options specified by one
or more `C`

= innerjoin(`A,B`

,`Name,Value`

)`Name,Value`

pair arguments.

For example, you can specify the variables to use as key variables.
