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

is there way call matlab functions outside, in particular windows cmd (but linux terminal, lua-scripts, etc...), without opening new instance of matlab each time?

for example in cmd:

matlab -sd mycurrentdirectory -r "function(parameters)" -nodesktop -nosplash -nojvm 

opens new instance of matlab relatively fast , executes function. opening , closing of reduced matlab prompt takes 2 seconds (without computations) - hence 4000 executions more 2 hours. i'd avoid this, called function located in same workspace. can done in same instance always?

i did research , found possibility of matlab com automation server, seems quite complicated me , don't see essential steps make work case. advices that?

i'm not familiar c/c++/c# i'm thinking use of python (but in worst case).

based on not-working, thought, idea of @ilya kobelevskiy here final workaround:

 function pipeconnection(numiterations,inputfile)   i=1:numiterations   while(exist('inputfile','file'))       load inputfile;      % read inputfile -> inputdata      output = myfunction(inputdata);       delete('inputfile');  end   % write output file  % call external application process output data  % generate new inputfile    end; 

another convenient solution compile executable of matlab function:

mcc -m myfunction 

run .exe-file using cmd:

cd mycurrentdirectory && myfunction.exe parameter1 parameter2 

be aware parameters passed strings , original .m-file needs adjusted considering that.

further remarks:

• i guess matlab still needs installed on system, though not necessary run it.
• i don't know how far method limited respectively complexity of underlying function.
• the speed-up compared initial apporach given in question relatively small
