The arguments are passed from program1 is to be considered as input for program2. program2 have to work with these inputs and it iteratively give the results. Now each and every iteration that results have to be used as input to program1.Both have to made simultaneously.Is it possible to make this?kindly give answers.

You can use the parallel computing toolbox with a pool of size 2. use spmd and test labIndex to determine which of the two programs you need to execute. The two parts should use labSend and labReceive to communicate.

在 MATLAB Online 中打开

parpool(2)
spmd
  first_run = true;
  while true
    if labIndex == 1
       if first_run
          A_parameters = initial_parameters_for_A;
          first_run = false;
       else
          A_parameters = labReceive();
       end
       A_output = A(A_parameters);
       B_parameters = make_B_parameters(A_output);
       labSend(B_parameters, 2);
    else
       B_parameters = labReceive();
       B_output = B(B_parameters);
       A_parameters = make_A_parameters(B_output);
       labSend(A_parameters, 1);
    end
  end
end
