how can i run m file in a active sesion from command promt?

I'm wrting an algorithm for software by compiling my code using deploytool. the interaction with the software is with text files:

my_algorithm.exe in.txt out.txt

for debug i want to run the code from mathlab using breakpoints and the environment. i know i can run it using:

<matlabroot>\bin\matlab.exe -r my_algorithm.m

however, it will open a new sesion every time which will takes a lot of time and wont remeber my breakpoint.

is there a way to run the function without opening a new sesion every time.

A brute force solution:

using the software cmdow i meneged to do this in 4 steps: 1. download cmdow from the link: http://www.commandline.co.uk/cmdow/ 2. write a robot matlab code that types like a real person:

function keyboard_robot(varargin)
%types the input as if a user typed it and then press enter
%keyboard_robot(command)

%import
import java.awt.*; 
import java.awt.event.*; 
rob = Robot;

%extract ascii code from string
mytext = double(varargin{1});

%init the numpad keys
keys = arrayfun(@(d)eval(sprintf('KeyEvent.VK_NUMPAD%d',d)),0:9);

%loop over all characters
for textInd = 1:length(mytext)
    %enter the key using ALT + <ascii code> 
    %hold ALT
    rob.keyPress(KeyEvent.VK_ALT);
    %loop on digits of each ascii code
    for iDig = 3:-1:1
        %take the current digit
        dig = floor(mod(mytext(textInd), 10^iDig) / 10^(iDig - 1)); 

          %press the digit
          rob.keyPress(keys(dig + 1))
          pause(0.02)
          rob.keyRelease(keys(dig + 1))
      end
      %release ALT
      rob.keyRelease(KeyEvent.VK_ALT);
  end

%press Enter
rob.keyPress(KeyEvent.VK_ENTER);
rob.keyRelease(KeyEvent.VK_ENTER);

end
3. compile the function into EXE
4. write a bach file to use the two EXEs:

for /f "tokens=1,9" %%a in ('cmdow /t') do (
   if /i "%%b"=="MATLAB" cmdow %%a /ACT
 )
keyboard_robot %1

just start the back with parameter of the command: c:\folder> run_matlab_from_cmd.bat my_function(myParameters)

IMPORTENT: i couldn't find a way to move to command window so befor running make shure that the command window is in focus!

enjoy.
