The AMPL API can function as an add-on to any existing AMPL installation. If you do not yet have an AMPL installation on the computer where you will be working with the API, see our demo page or trial page to download a working version that can be installed quickly.
Follow the instructions on our AMPL API
page to download the API package appropriate to your platform, and to add
the downloaded folder (directory)
amplapi to your AMPL installation.
Open the MATLAB application window and set the path to
amplapi/examples/matlab. Enter the following to initialize the session
and then run an example:
setupOnce firstExample <solver>
<solver> is the name of a solver that has been installed with AMPL.
(If a solver is not specified, then AMPL’s default choice will be used.) This will solve
several small diet problems and then display the optimal amounts of the foods
from the last solution.
setUp function defined in
amplapi/matlab/setUp.m from your
MATLAB code to add
ampl-1.3.1-0.jar to the class path. Together with your existing
AMPL implementation, this will provide the full object library and access to
all AMPL functions.
amplapi folder (directory) can be moved to a different location in
your computer’s filesystem, provided that the location of your AMPL executable
ampl.exe) has been placed in the system search path.
To deploy AMPL API applications to users who do not have their own AMPL
installations, include with your MATLAB application the AMPL executable
ampl.exe); the folders (directories)
amplapi/matlab; binaries needed to run any solvers that are used; and an
appropriate license file for AMPL and solvers.
