In this exercise, you had better employ sim() to run your Simulink model from MATLAB environment. To achieve your goal of collecting simulation results after every simulation, you should use:
(1) In Simulink model, use [From WorkSpace] and [To WorkSpace] blocks, which are used to get the data from MATLAB to simulate the model and send the results back to MATLAB workspace.
(2) In MATLAB code, use sim() to run the SImulink model within a loop. E.g.:
K = ...; % 256 - by - 256
for ii = 1:256
A = K(ii,:); % Call each row of data from [K] and use for simulation. [From WorkSpace] variable's name is A
OUT(ii)= sim('M_Run.slx'); % Simulink model called M_Run.slx. All simulation results saved under the var name OUT (that can be set up as structure or array)
end
