# tensor -- tensor product

## Description

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

This method is declared as a MethodFunctionBinary, so for two or more argument the product is computed iteratively from the binary tensor products, working from left to right. For two arguments, this is the same as A ** B except that options are allowed.

 i1 : tensor(ZZ^2, ZZ^3, ZZ^4) 24 o1 = ZZ o1 : ZZ-module, free

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).
