Matlab doesn't release the C code execution until completion of the script

The C app send command to the matlab for script M file launching and the matlab doesn't release the C code execution, return from call function, until the m script completion. How to resolve this issue. How C code can run m script and continue to execute other operators and functions?

ex:

const char ptrMatlabCommandStart[] = "run(\"example.m\")";

ep = engOpen(NULL); // open C2M engine
engEvalString(ep, ptrMatlabCommand) // launch example.m script
a = b;  // can't be performed until end of the example.m script

Also very interaesting following implementation of C code functionality:

1. pa = mxCreateDoubleScalar(value); // initialize in matlab worklspace by C code
2. mxSetDoubles(pa, value); // set value in matlab worklspace by C code
3. engEvalString(ep, ptrMatlabCommand); // launch matlab script that use value

for ()

{

4. mxSetDoubles(pa, value); // update value in matlab worklspace by C code and impact to matlab script results

// matlab script computes according to the new value - parameter

// matlab also can change value according to launched script

}

5. value = *mxGetDoubles(pa); // read updated value in C app

MATLAB is essential sequential/blocking behavior. Whereas you call a function from C or Matlab yo have to wait until completion.

However if you have recent MATLAB you can run a function (restricted capability) in background and get the hand back instantanously using parfval
