%% GERAD NOMAD Build for Matlab

% This file will help you compile NOMAD for use with MATLAB. 

% To recompile you will need to get / do the following:

% 1) Get NOMAD
% NOMAD is available from https://www.gerad.ca/nomad
% Complete the download form then download the latest version. Define the
% $NOMAD_HOME environment variable.

% 2) Start Matlab and go into $NOMAD_HOME/examples/interfaces/Matlab_Mex
% The NOMAD MEX Interface is a simple MEX interface written to use NOMAD.

% 3) Compile the MEX File by executing this file in Matlab
%
%
% The code below will build the NOMAD MEX file and set the Matlab path. 

clear nomad

% Current directory
cdir = cd;

% Check and set nomad_home and create variables for path
clear nomad_home nomad_src;
