Create A Standalone Executable for MATLAB calling Fortran and C

MEX Standalone Folder

1. batch_standalone -- batch script for standalone
2. make.m -- m-file to compile this example completely
3. mexStandalone.zip -- zip file of this directory
4. mybash.txt -- append to your .bashrc file
5. mycsh.txt -- append to your .cshrc file
6. README.html -- this file
7. runx2.m -- main m-file (calls Fortran and C apps)
8. submitmjobs -- script to launch multiple batch jobs (optional)
9. times2.c -- Mathworks' C example (with gateway) to perform multiply
10. timestwo.F -- Mathworks' equiv. Fortran example (with gateway)

Procedures for generating and running standalone

1. If you do not have access to Boston University's Shared Computing Cluster (SCC), you may download the mexStandalone.zip file.
   Upon unzipping it, follow the steps starting from "cd mexStandalone"
2. If you have access to Boston University's Shared Computing Cluster (SCC), it is more convenient to
   

   scc1% cp -r /project/scv/examples/matlab/misc/mexStandalone your-preferred-path
   scc1% cd mexStandalone

3. Code compilations and running

   function runx2(n)
   %function runx2(n)
   % Purpose: Simple demonstration of calling Fortran and C codes for 
   %          multiplying an input, n, by 2. This program is used to 
   %          demonstrate:
   %          1) use of mex to compile C and Fortran codes
   %          2) calling procedure of these C/Fortran mex files
   %          3) use of mcc to generate standalone to run outside MATLAB
   % Input:
   % n -- this will be multiplied by 2
   % Procedure:
   % >> mex timestwo.F  % compile fortran file with F suffix
   % >> mex times2.c    % compile C file
   % Generate standalone with -m; non-m-files added to standalone with -a
   % >> mcc -m runx2.m -a timestwo.mexa64 times2.mexa64
   % Run executable runx2 outside of MATLAB
   % scc1% runx2 5
   % data passed with command syntax are strings; need conversion for double
   if ~isdeployed, disp('Cannot run as m-file.'), return, end
   n = str2double(n);
   mf=timestwo(n);   % run fortran mex file to compute mf = n x 2
   disp(['n = ' num2str(n) '  ;   mf = n x 2 = ' num2str(mf)])
   mc=times2(n);     % run C mex file to compute mc = n x 2
   disp(['n = ' num2str(n) '  ;   mc = n x 2 = ' num2str(mc)])
   exit
   

4. Append mysch.txt and mybash.txt to .cshrc and .bashrc in your home directory

   scc1% cat mycsh.txt >> ~/.cshrc
   scc1% cat mybash.txt >> ~/.bashrc

5. To make the changes effective immediately

   scc1$ source ~/.bashrc     <== if you run the bash shell
   scc1% source ~/.cshrc      <== if you run the csh shell

6. Running in batch mode
   For instructions on running batch jobs on the SCC, visit the standaloneDemo folder.
