Affine is a collection of programs for algebraic computing. It currently uses maxima for some of the basic routines, as well as for display. If you have an executable 'saved_affine' you may just invoke that, or make a link to some place where executables are usually kept: ln -s /public/affine/saved_affine /public/bin/affine The maxima-*/info documentation covers maxima and affine. Much of the internal computation is done with polynomials or rational functions in simplified form. Some functions for dealing with these: (st-rat form) --> internal format n*,n+, n- ,nred, n. take general or internal format arguments, always coercing to internal format. psublis, pcoeff, list-variables are some heavily used routines. The correspondence between variables and internal variables is 1-1 unlike ordinary maxima rat format. (new-disrep form) and (fake-header form) put polynomials back into a format for maxima. fast_linsolve and other programs in the sparasemat.lisp file try to do a better job than maxima for large matrices. COMPILING AFFINE: (load "sysdef.lisp") (make:make :affine :compile t) LOADING AFFINE: (load "sysdef.lisp") (make:make :affine) Notes: You may want to change to proclaim about safety in sysdef.lisp 0 will give maximum speed, but minimum error checking. A function called with the wrong type arguments on safety 0, can give a segmentation fault very easily. If you are using akcl, you could usde the makefile and do make saved_affine to save out an image which can be reused without loading the files. This will also look after compiling things. There is a tiny bit of documentation at the end of the maxima/doc/DOC file (eg grobner_basis, set_up_dot_simplifications,..) and of course there are the sources. I know documentation should be much better. Ask me a question, and I will probably add it to the doc file too.
