Directories edit

Start Maxima and type the command:[1]

   maxima_userdir;

this will tell you the directory that is being used as your user directory.

infolists edit

  • is a system variable
  • Default value: []
  • is a list of the names of all of the information lists in Maxima. These are
    • labels : All bound %i, %o, and %t labels.
    • values : All bound atoms which are user variables, not Maxima options or switches, created by : or :: or functional binding.
    • functions : All user-defined functions, created by := or define.
    • arrays : All declared and undeclared arrays, created by :, ::, or :=.
    • macros : All user-defined macro functions, created by ::=.
    • myoptions : All options ever reset by the user (whether or not they are later reset to their default values).
    • rules : All user-defined pattern matching and simplification rules, created by tellsimp, tellsimpafter, defmatch, or defrule.
    • aliases : All atoms which have a user-defined alias, created by the alias, ordergreat, orderless functions or by declaring the atom as a noun with declare.
    • dependencies : All atoms which have functional dependencies, created by the depends, dependencies, or gradef functions.
    • gradefs : All functions which have user-defined derivatives, created by the gradef function.
    • props : All atoms which have any property other than those mentioned above, such as properties established by atvalue or matchdeclare, etc., as well as properties established in the declare function.
    • let_rule_packages : All user-defined let rule packages plus the special package default_let_rule_package. (default_let_rule_package is the name of the rule package used when one is not explicitly set by the user.)

reset edit

reset : resets many (global) system variables

Use:

 reset()

example output :

 (%o1) [_, __, load_pathname, labels, %, linenum, ratprint, tr-unique, 
                                                     lispdisp, multiplicities]

trace edit

In Maxima :

:lisp (setf *debugger-hook* nil)


manual debuging edit

print partial results using :

  • print
  • playback

values edit

values:

  • is a system variable
  • is a list ... which contains the names of currently assigned scalar values which have been set by:
    • the user interactively
    • by packages which have been loaded"[2]
  • initial value is []

dependencies edit

dependencies :

  • is a system variable
  • is the list of atoms which have functional dependencies, assigned by:
    • depends
    • the function dependencies
    • gradef

status edit

 status (feature);

example output:
