Installing Existing MathLink-Compatible Programs
One of the most common uses of MathLink
is to allow you to call functions in an external program from within Mathematica
. Once the external program has been set up, all you need do to be able to use it is to "install" it in your current Mathematica
|Install["prog"]||install a MathLink-compatible external program|
|Uninstall[link]||uninstall the program|
Setting up external programs with functions to be called from within Mathematica.
This installs a MathLink
-compatible external program called bitprog
is one of the functions inside bitprog
You can use it just as you would a function within Mathematica
When you have a package written in the Mathematica
language a single version will run unchanged on any computer system. But external programs typically need to be compiled separately for every different type of computer.
has a convention of keeping versions of external programs in directories that are named after the types of computers on which they will run. And assuming that this convention has been followed, Install["prog"]
should always install the version of prog
appropriate for the particular kind of computer that you are currently using.
Using context names to specify programs to install.
When you ask to read in a Mathematica
language file using <<name`
will automatically search all directories in the list $Path
in order to find a file with the appropriate name. Similarly, if you use Install["name`"] Mathematica
will automatically search all directories in $Path
in order to find an external program with the name name.exe
allows you to install programs that are stored in a central directory without explicitly having to specify their location.
