Message-ID: <20071220012244-0800@axiom-wiki.newsynthesis.org>
Category: Axiom Mathematics => Axiom Interpreter
Originally Savannah bug #6490
The NAG interpreter and the Axiom interpreter do not accept the when and otherwise verbs when defining piecewise functions.
There are no library operations named when
axiomch : Integer -> UnivariatePolynomial(x,FRAC(INT))
Type: Void
axiomch(0) == 1
Type: Void
axiomch(1) == x
Type: Void
axiomch(n) == 2 * x * ch(n-1) - ch(n-2) when n > 1
Type: Void
axiomch(2) There are no library operations named when Use HyperDoc Browse or issue )what op when to learn if there is any operation containing " when " in its name. Cannot find a definition or applicable library operation named when with argument type(s) Integer Perhaps you should use "@" to indicate the required return type, or "$" to specify which version of the function you need. FriCAS will attempt to step through and interpret the code.
