5.1.111 prune

Syntax:
prune ( module_expression )
Type:
module
Purpose:
returns the module minimally embedded in a free module such that the corresponding factor modules are isomorphic.
Note:
If for the input module the attribute "isHomog" is set, prune also sets the attribute "isHomog".
For non-global orderings, only reduction steps with constant units are performed. Hence, the returned module does not need to be minimal.
Example:
 
See module.
