--How do I make Matlab call lots of little Matlabs?--

Here is a simple script that takes one parameter as input.

% simple.m  
disp(['you passed in',num2str(x)])
disp(['its cube is',num2str(x^3)])

I can run this from the command line

mymachine$ /Applications/MATLAB_R2010b.app/bin/matlab -nodisplay -nosplash -r "x=5;simple;exit"

What I would like is a way to call this script several times from within MATLAB thereby spawning independent MATLAB processes.

I had hoped it would be as simple as this:

% Control script
% Loop over an input variable and create several MATLABs
for param = 1:5
  funcstr = '/Applications/MATLAB_R2010.app/bin/matlab -nodisplay -nosplash -r ';
  scrstr = ['"x=',num2str(param),';simple;exit"'];
  command = [funcstr, scrstr];
  system(command);
end

But this seems to complete the commands sequentially rather than allowing them to run independently.

I would also rather avoid doing the control loop in a shell script if I can avoid it. Doing the loop in Matlab seems to afford me much more flexibility.

Any advice on how to do this very simple thing without the toolbox?
