execute .exe in subdirectories?

Hi,
The .exe I am using doesn't work well when calling files outside its current working directory. So I have copied the .exe to each of the subdirectories (ie mote carlo iterations). However, my code as written is, I think, using the original .exe, and not running the copies in each path{i}. The exe defaults to looking in its current working directory for the files it needs.
How would I re-script the bottom segment of code so that I am running the copies of the .exe in each path{i} ?
clear all;

%Solute transport parameters in row 47 of SELECTOR.IN file

% variable. The code reads the reference Selector.in, copies the first 46 lines to the new file, write the van Genuchten parameters to the 47th line,
% and finally copies the last 10 lines from the reference Selector.in to the new file.

for k=1:(skip_lines)

%Whatever the solute transport parameter is for that monte carlo run (i)

% %f = Fixed-point notation (Use a precision operator to specify the number of digits after the decimal point.)
% '\n' as a newline indicator.
fgetl(fileID_in); % returns the next line of the specified file, removing the newline characters.
skip_lines_end=5; % CORRECT NUMBER??? DOUBLE CHECK
for k=1:(skip_lines_end)
x=fgetl(fileID_in);
fprintf(fileID_out,'%s\n',x);
end
fclose('all');
end
%SECTION THAT NEEDS WORK...I THINK CODE AS WRITTEN IS CALLING ORIGINAL
%.EXE, BUT i WOULD LIKE THE .EXE COPIES IN EACH PATH{i} TO EXECUTE AND CALL
%THEIR RESPECTIVE PATH{i} FILES. HOW SHOULD I CANGE THIS SECTION TO DO
%THAT?
for i=1:num_sim
exec_path=['"' hydrus_exec '" "' path{i} '"'];
[x, y]= dos(exec_path);
if x % unsuccessful
error('exe failed'); % or take some other action besides throwing an error
end
end
Many thanks!!!

While I appreciate the constructive leads and the agreement that this .exe is most likely follows bad programming practices, is there anyone who might be able to help me out with my original question of scripting my above code so that each copy of the .exe is executed? In the interest of time, I would rather not go back to the drawing board at this point and would like to work with what I have if possible. TIA for your time.

To call each copy of the .exe, with no input arguments to the .exe (may work - who knows, worth a shot):
for i=1:num_sim
exec_path=['"' fullfile(path{i},'H1D_CALC.exe') '"'];
[x, y]= dos(exec_path);
if x % unsuccessful
error('exe failed'); % or take some other action besides throwing an error
end
end
To call each copy of the .exe with one input argument, which is the name of the directory it resides in (same as you were doing before with a single .exe, except now the .exe you're running is in that same directory each time):
for i=1:num_sim
exec_path=['"' fullfile(path{i},'H1D_CALC.exe') '" "' path{i} '"'];
[x, y]= dos(exec_path);
if x % unsuccessful
error('exe failed'); % or take some other action besides throwing an error
end
end
