In ugUserMake , you learned how to use the operation function to create a function from symbolic formulas. Here we introduce a similar operation which not only creates functions, but functions from functions.
The facility we need is provided by the package MakeUnaryCompiledFunction(E,S,T). MakeUnaryCompiledFunction This package produces a unary (one-argument) compiled function from some symbolic data generated by a previous computation. MakeBinaryCompiledFunction is available for binary functions. MakeBinaryCompiledFunction The tells where the symbolic data comes from; the and give Axiom the source and target type of the function, respectively. The compiled function produced has type -> . To produce a compiled function with definition , call from this package. The function you get has no name. You must to assign the function to the variable to give it that name.
Do some computation.
Convert this to an anonymous function of . Assign it to the variable to give the function a name.
Apply the function.
