intersect -- compute an intersection

Description

This function calculates the intersection of a list or sequence of compatible objects.

When a more efficient algorithm is available for computing the intersection of all inputs simultaneously rather than iteratively, for instance for intersecting Modules, a specialized function that takes a list or sequence may be installed on (symbol intersect, Type).

i1 : code lookup(symbol intersect, Module)

o1 = ../../../../Macaulay2/m2/option.m2:15:14-18:8: --source code:
       (opts,f) -> args -> (
            -- Common code for functions created with >> to process options and arguments.
            uncurry(f, override (opts,args))
            )

     | -- option table opts:
     | OptionTable{MinimalGenerators => true}
     |             Strategy => null

This function may also be called using the synonym intersection.
