5.1.74 liftstd

Syntax:
liftstd ( ideal_expression, matrix_name )
liftstd ( module_expression, matrix_name )
liftstd ( ideal_expression, matrix_name, module_name )
liftstd ( module_expression, matrix_name, module_name )
Type:
ideal or module
Purpose:
returns a standard basis of an ideal or module and the transformation matrix from the given ideal, resp. module, to the standard basis.
That is, if m is the ideal or module, sm the standard basis returned by liftstd, and T the transformation matrix then matrix(sm)=matrix(m)*T and sm=ideal(matrix(m)*T), resp. sm=module(matrix(m)*T).
In an optional third argument the syzygy module will be returned.
Example:
 
See ideal; matrix; option; ring; std.
