  I have two listeners for event but according to   documentation , "the order in which listeners execute is not defined". I want to check whether one callback has executed before the next without having that callback generate it's own event. Is there a way of doing this?   For example:   event: PayDay   listener callbacks: UpdateBankAccount, GoShopping   How can I ensure that UpdateBankAccount has ocurred before GoShopping?

If you implement the event provider yourself, it is possible to track which event listeners were fired before a specific callback.   You can implement a daughter class of event.EventData (I called

  Hello, I use this code which is linked to a   Simulink   file to   simulate   and get data used for Artificial Neural Network. The data shown below are saved in structur format and each case contains 30001 data.   So I want to arrange data to get only one matrix with 2 rows and (30001*6) lines by modifying the matlab code or, save directly the data acquired from MDL file under a matrix of 2 lines and 180006 lines.   Thank you. j=1; for ref_P=10:1:12; for ref_Q=-10:1:-9; options = simset('SrcWorkspace','current'); S = sim('gti_V3_15_NN',[],options); %%%%%%%%%%%%%%%%%%%%%%%%%%% Delta =data_out(:,1); % from workspace Vom =data_out(:,2); %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% out(j).Delta=Delta; out(j).Vom=Vom; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Ref_P(j,1) = ref_P; Ref_Q(j,1) = ref_Q; %%%%%%%%%%%%%%%%%%%%%%%%%%% j= j+1; end end   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  for students,

  What are the general guidelines for choosing ODE solvers for   simulating   a model using   Simulink ? I want to know the basic procedure to be followed in choosing solvers from Configuration Parameters while simulating a Simulink model.

It means the model should be tuned a little bit to get good simulation results. The following are some heuristic rules to help user select the solver and verify the simulation results and tune the model.   1 Variable-step solver:   When simulating a model, if possible, always start with a variable step solver (a goo

  Hi everyone,  I have a   simulink model  simultaing a periodic continuous system in the form: dx(t)=A(t)x(t)+B(t)u(t) with A(t+T)=A(t) and B(t+T)=B(t) In every instant i compute the matrices A(t) and B(t). I am introducing a Kalman filter, but i can't figure out how to insert variable matrices in the   simulink block . What is the best way to do it? Thanks in advance for the help.

For this use case, I would suggest creating a variable of type   Simulink.Parameter  in the base workspace.     x = Simulink.Parameter x.Value = [1 1 1 ; 2 2 2]; The above will create a variable x of   Simulink.Parameter  where the   Value  field is

  Hello, I wrote a function which needs a (t) as input and it graphs something i want to marker the point which user inputs on the graph for example if user defines t=10 I want to marker the graph on point t=10 and x(t)=10. how should I do that. here is my code     function x=calcDisplacement(t) m=1100; k=570; c=430; x0=0.05; v0=0; omega_d = sqrt((4*m*k)-(c^2))/(2*m); sigma = c/(2*m); alpha = x0/2; beta = -((v0+x0)/(2*(omega_d))); displacement=@(t) 2*exp(-2*(sigma).*t).*(((alpha)*cos((omega_d).*t))-(beta)*sin((omega_d).*t)); x=displacement(t); fplot(displacement,[0 50],'color','blue') ylim([-0.1 0.1]) legend ('Displacement of suspension') ylabel('Displacement(m)') xlabel('Time(s)') title('Graph of displacement in car suspension') hold on; end   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  for students, engineers and r

  I am using xPC Target Encoder blocks in my   Simulink model.   I would like to know how to handle potential register rollover.

For previous product releases, read below for any possible workarounds:   Encoder boards have a fixed size counter register of 16 bits, 24 bits, or 32 bits. Regardless of the size, the register always eventually overflows and rolls over. This can happen in either the positive or negative direction.   Some boards provide a hardware mechanism to account for overflows or rollovers. As a best practice, you should design your model to always deal

  Hi,   My  Simulink   simulations  are governed by a large set of .m files and rather than starting the simulation on my own with Play button, I prefer to call an .m-file which sets up the environment and then starts the simulation.   I run my simulation with   set_param('main','SimulationCommand','start'); However, this call is non-blocking. Is there a good way to block the m-file until the simulation is completed?   I could use polling in a for loop (querying for the state over and over again) but this is clearly not considered a good solution.   I could use the "sim" command but I do not want this because I do not "see" Simulink running (including the states, simulation time etc)   Ideally there would be a "blocking" option to the "SimulationCommand" "start".   Another solution I could think of (not sure if this is supported by MATLAB?) to create an event and let the matlab script wait for an event to signal

This can include mixtures of components that model analog world code for microprocessor type A code for microprocessor type B code for FPGA type C code for ASIC design D ... Model Reference is a key feature for separating components that represent code for different targets.   In  Alberto's model reference introductory video  at time 3:29, he mentions that
