[268] | 26 | ;; DETAILS: This file implements an interface between the Grobner
|
---|
[269] | 27 | ;; basis package NGROBNER and Maxima. NGROBNER for efficiency uses its
|
---|
| 28 | ;; own representation of polynomials. Thus, it is necessary to convert
|
---|
| 29 | ;; Maxima representation to the internal representation and back. The
|
---|
| 30 | ;; facilities to do so are implemented in this file.
|
---|
[268] | 31 | ;;
|
---|
[270] | 32 | ;; Also, since the NGROBNER package consists of many Lisp files, it is
|
---|
[271] | 33 | ;; necessary to load the files. Unfortunately, it is not quite
|
---|
| 34 | ;; possible to use ASDF for this purpose, although NGROBNER can be
|
---|
[272] | 35 | ;; loaded into lisp using ASDF. Perhaps one day... For now,
|
---|
| 36 | ;; we use LOAD to accomplish this task.
