I am very frustrated that, after a year with Mathematica, I still cannot
create and use packages. I must be missing something elementary.
Here is what I have attempted. I think there is just one missing part:
Step 1: "write" a package:
In the tutorial "Setting Up Mathematica Packages" there is source for the
sample package "Collatz.m". I copied that source and pasted it into a new
Mathematica file, then used the "Save As" command to save the file as a
package, naming it "collatz.m" and placing it in a folder called packages.
Step 2: Try to use the package:
1. I create a new Mathematica notebook file, put the following five lines in
it, and save it as "collatz.nb" alongside "collatz.m":
(* missing step; neither << collatz.m nor Import["collatz.m"] works *)
Collatz (* 'Collatz' remains undefined *)
Executing the above code, the output from "FileNames" shows that both files
exist in the directory. So what code should replace the fourth line above?
Or have I gone astray elsewhere?
