I want one plot to display the results of 100 model runs. Do I have to use Excel or is there a way within Netlogo?
I found the proposal to use create-temporary-plot-pen, but i did not manage to find out how this will do the job.
Don't use clear-all, as it will clear all of the plots. Start each run by using a more limited set of clearing commands (e.g., clear-turtles, clear-patches, reset-ticks, and so forth). Then each run can add data to an existing plot.
If you do this you may want to offer your user multiple setup buttons, one that clears everything, and one that only sets up the current run.

In a live script in matlab, I plot multiple figures, and I use this code to enumerate the figures:
FigureQuantity=1
plot(data_1)
title('Figure '+string(FigureQuantity))
Then on another code section I do it again
FigureQuantity=FigureQuantity+1
plot(data_n)
title('Figure '+string(FigureQuantity))
The problem is that if I run the last code section again, FigureQuantity gets updated and the enumeration of figures gets broken.
There is any way to get the number of tokens ordered by his code appearance on the live script? (independent of how many times the section code is run)
I would like to keep tokens so I can mix inserted images and plots. And I want to export the document as PDF (not to show plots in an application or an independent window).
What I need is something like MS Word enumeration of figures and tables.
I found this Matlab documentation: Number Section Headings, Table Titles, and Figure Captions Programmatically, but it appears to be used for creation of MS Word or HTML documents, and not to enumerate images on Matlab live scripts.
I do not understand how to use it, or if that is his purpose on Matlab.
I'm assuming you're updating the data_n variable live as well; otherwise, if you're defining these variables manually then not doing so for the figure variables isn't really the solution I think you're looking for.
Why not for-loop through the figure updates?
for FigureQuantity = 1:numberOfFigureQuantities
figure(FigureQuantity);
hold on;
plot(data_n(FigureQuantity))
title(strcat('Figure Number: ',num2str(FigureQuantity)));
end
The figure count corresponding to the FigureQuantity will index the appropriate figure and will update that figure if it already existed. This is the solution I think you're looking for; if not, please clarify.
I am running Netlogo program to simulate if a drunk person manages to cross to another side of the pier safely. I then stored this result in a global variable.
Now I would like to run a repetition of this simulation 100x through BehaviorSpace to find out the percentages of different outcomes.
However, I am unable to extract the value of that variable at the end of each repetition.
I would like to ask if there are any ways I can extract the value of a global variable at the end of each repetition in BehaviorSpace.
Thank you.
You can just at the global to Measure runs using these reporters.
If you only want the last result, uncheck Measure runs at every step.
If you have other things you want to report every step and you insist on not recording the global at every step, you can add to Final commands to write the value to a separate file.
For Matlab simulink, how does one go about generating multiple step function at different conditions for a system
I am trying to simulate a simple flow through a tank and controlling the temperature within. At various interval say time at 10ses and 20secs i intend to draw out different flowrate/flow amount of water.
With the system designed, how do I show on a single scope how Flow in changes with the different amount of flow out drawn.
Appreciate any kind advises
There are many different ways of doing this, for example defining the data in MATLAB and using a From Workspace block or using multiple Step blocks summed together appropriately. But to start I'd suggest you look at the Signal Builder block.
To view multiple signals at once in the same Scope, either set the scope up to have multiple inports, or Mux the signals together and feed them in in the usual way.
Hi I want to run two or more simulink model in parallel and synchronisation. is there any way to do it? One way I think is by creating a subsystem and put all models inside it. It should run parallely. This one is not prefered for me. I want to open two matlab instances and run two different model in synchronisation. is this possible? I want to do it programmatically. Any help is appreciable.
You should use a matlab script and implement the synchronization logic in it.

You can execute the simulink model by simply calling it from a Matlab Script.
You have to define a task containing the next steps: First you can calculate inputs in Matlab. Then execute the first model with the first inputs. Then save the results to a certain variable. Finally use that variable on the second model and launch second model simulation.
Repeat the task for all the necessary steps.
If you have the Instrument Control Toolbox, you can send/receive data between the two models via TCP/IP or UDP/IP blocks. No need to have two MATLAB sessions, this can be done from one MATLAB session, see this loopback example.
However, I would query the need to have two separate models. Why not put both models in the same model as subsystems, or even as Model blocks if you want to keep the atomic nature of each sub-model?
The best way to run parallel simulink simulations is probably the parsim command. Their is a complete article on the Mathworks website explaining how to do it:
Run Parallel Simulations
I have some programs written in Matlab that I need to run several times for some reasons (debugging, testing with different input, etc...)
But, there are a lot's of graphs that are plotted by the programs and its various functions such that everytime I run the program, I have to wait for all the graphs to be displayed, which is very annoying and time consuming (especially when you are working with a small laptop).
After the program is executed, I close them with a close all.
So my question is:
Is there a way to disable all plots/figures/graphs in Matlab? either in the options, or by executing a certain code like disable plot and enable plot to ensure that no figures are being displayed.
I know that I can just browse the code and comment the plotting part, but I don't want to forget to uncomment.
Try some combination of the two commands:
set(gcf,'Visible','off') % turns current figure "off"
set(0,'DefaultFigureVisible','off'); % all subsequent figures "off"
The second one, if you put it near the beginning of your program, might do the trick for you. Of course, it is still creating the plots, which might be undesirable for computation time and/or RAM issues.
This is a classic reason to avoid Matlab when one can. It fosters bad programming design. To solve this problem correctly, you should create something that lets you "flip a switch" at the highest level of your program and control whether plots show or do not show. Perhaps it even has gradations of the show/don't show option so you can select different types of plots that do/do not show depending on what diagnostics you are running.
Ideally, you'd want this "flip a switch" creation to be a class that has access to visibility and plot functions of other objects. But because interactive object-orientation is so cumbersome in Matlab, it's often not worth the effort to develop such a solution, and most people don't think about this design aspect from the outset of their project.
Matlab would encourage someone to solve this by making flag variables like "isPlotVisible" or something, and creating functions that always accept such flags. I agree this is a bad design.
You could run matlab from the command line with:
matlab -nojvm
but then you don't get the GUI at all. Alternatively, you could write a file 'plot.m':
function h = plot(varargin)
h = [];
end
which doesn't do anything. If this is in the working directory (or somewhere else near the top of the path), then plot will call your function instead of the 'real' plot. You'd need to do the same from any other graphing functions you call.
The closest way I know of 'turning off plotting' would be a folder of such functions that you can add to the path to disable plotting, and remove to enable.
The previous methods are fine, but an easy and good habit to take is to use a "on/off parameter". So basically, at the beginning of your code, you can add something like:
DisplayFigure = 1; %1 = display, 0 = no display
After that, add "if DisplayFigure == 1 ... end" for all your plotting related commands, where the commands should be inside the if statement (the ... above). Hence you won't even compute the plots, which will save you a lot of time and memory. You just have to change the value of the variable "DisplayFigure" to plot or not the figures.
