Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
-- System variable: values Initial value: []
values
is a list of all bound user variables (not Maxima options or switches). The list comprises symbols bound by :
, or ::
.
If the value of a variable is removed with the commands kill
, remove
, or remvalue
the variable is deleted from values
.
See functions
for a list of user defined functions.
Examples:
First, values
shows the symbols a
, b
, and c
, but not d
, it is not bound to a value, and not the user function f
. The values are removed from the variables. values
is the empty list.
(%i1) [a:99, b::a-90, c:a-b, d, f(x):= x^2]; 2 (%o1) [99, 9, 90, d, f(x) := x ] (%i2) values; (%o2) [a, b, c] (%i3) [kill(a), remove(b,value), remvalue(c)]; (%o3) [done, done, [c]] (%i4) values; (%o4) []
There are also some inexact matches for values
. Try ?? values
to see them.
(%o1) true (%i2)
