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.
Function: remfunction (<f_1>, ..., <f_n>)
Function: remfunction (all) Unbinds the function definitions of the symbols <f_1>, ..., <f_n>. The arguments may be the names of ordinary functions (created by := or define) or macro functions (created by ::=).
remfunction (all) unbinds all function definitions.
remfunction quotes its arguments.
remfunction returns a list of the symbols for which the function definition was unbound. false is returned in place of any symbol for which there is no function definition.
