Call a function by an external application without opening a new instance of Matlab

by

Based on the not-working, but well thought, idea of @Ilya Kobelevskiy here the final workaround:

 function pipeConnection(numIterations,inputFile)

 for i=1:numIterations

 while(exist('inputfile','file'))

     load inputfile;
     % read inputfile -> inputdata
     output = myFunction(inputdata);

     delete('inputfile');
 end

 % Write output to file
 % Call external application to process output data
 % generate new inputfile 

 end;

Another convenient solution would be to compile an executable of the Matlab function:

mcc -m myfunction

run this .exe-file using cmd:

cd myCurrentDirectory && myfunction.exe parameter1 parameter2

Be aware that the parameters are now passed as strings and the original .m-file needs to be adjusted considering that.

further remarks:

  • I guess Matlab still needs to be installed on the system, though
    it is not necessary to run it.
  • I don’t know how far this method is limited respectively the complexity of the
    underlying function.
  • The speed-up compared to the initial apporach given in the question is
    relatively small
