Chapter 4 – Files

Publisher Summary This chapter explains various types of packages, their loading, and what to do if one forgets to load a package. The chapter also describes exporting and importing of files, including export import data, graphics, and locating the files. Having plenty of random access memory (RAM) is very good; the more memory Mathematica has, the speedier it is. A good way to save time may be to use a remote kernel. If your machine is not powerful enough, you can save time by using the greater power of a remote machine. Avoiding the use of “arbitrary-precision” numbers will be helpful because calculations with these numbers are much slower than calculations done with the hardware-implemented, machine-precision numbers. These are versatile commands to use for the writing and reading of data and graphics in more than 100 formats. One method of saving memory is to run only the front end on your machine and to run the kernel in another machine. Then only the front end takes memory from your machine, and you can take advantage of the possibly larger RAM and speedier processor of the remote kernel.
