A FramedModule is a finite rank free module with fixed R
-module basis.
basis()
returns the fixed R
-module basis.
convert([a1, .., an])
returns a1*v1 + ... + an*vn
, where v1
, ..., vn
are the elements of the fixed basis.
convert(a)
returns the coordinates of a
with respect to the fixed R
-module basis.
coordinates([v1, ..., vm])
returns the coordinates of the vi
's
with to the fixed basis. The coordinates of vi
are contained in the i
th row of the matrix returned by this function.
coordinates(a)
returns the coordinates of a
with respect to the fixed R
-module basis.
rank()
returns the rank of the module
represents([a1, .., an])
returns a1*v1 + ... + an*vn
, where v1
, ..., vn
are the elements of the fixed basis.
