Maxima/Debugging

Directories Start Maxima and type the command:[Maxima] Phantastic Program! One bug - discussion maxima_userdir; this will tell you the directory that is being used as your user directory. infolists 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 reset : resets many (global) system variables Use: reset() example output : (%o1) [_, __, load_pathname, labels, %, linenum, ratprint, tr-unique, lispdisp, multiplicities] trace In Maxima : :lisp (setf *debugger-hook* nil) manual debugging print partial results using : print playback values 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"Maxima by Example: Ch. 1, Introduction to Maxima ∗ Edwin L.
