Is there any method to translate MATLAB ABM model to NetLogo? I want to make changes in an existing MATLAB Model by importing it in Netlogo. I have no know-how about MATLAB.
Short answer, no. There is an extension (see https://github.com/mbi2gs/netlogo-matlab-extension/wiki) to, for example, transfer variable values between Matlab and NetLogo, but there is no way to turn Matlab code into NetLogo code.

I would like to create a project using a Matlab simulink environment model to find optimal parameters using reinforcement learning. Is it possible to export the environment data from matlab simulink and incorporate it into a python script or to create an interface to matlab simulink in order to train interactively with it? Or is there a better approach?
Unfortunately, this is rather vague, so I'm sorry, as I do not know what the matlab model will look like. It would also be helpful for me to see an example project or something along the lines of accessing Matlab Simulink data and reinforcement learning.
Thank you very much.
To create an interface with python script and the Simulink simulation, you can use MATLAB Engine for Python.
I could find a sample implementation in this blog. You can extend the simulate function in this example with an RL Agent to determine an action.
You can use simulink and generate coder from simulink. You must download simulink coder, matlab coder packages to generate code.
I have simmechanics model in simscape, I have imported it from solidworks design
I'm able to get linearized model using linmod and it is okay as any system in simulink
The problem here that I want to get the differential equations for that system, Is there any way to extract them?
The short answer: no, there is no built-in functionality.
The long answer: you'd have to parse the Simscape network, query the source equations (if the source code is visible). And stack these together. That's a pretty involved workflow.
I know there are several functions, such as aryule and arborg, which can estimate coefficients of AR models. But these functions cannot deal with AR models with input-output delay.
I also learned that the newest Matlab includes a function named 'arx' that can estimate AR parameters including the input-output delay. Unfortunately, the current version of Matlab I used is 2013a and I didn't find this 'arx' function inside.
I am wondering if anybody would kindly help me to tackle this issue.
I have a large simulink model with many source and sink blocks, many with only elementary arithmetic operations in between. I have been asked to document the equations behind the model. I am currently doing this manually and I am finding it rather slow and there is a relatively high chance of errors in the process.
Is there any way for Simulink to generate the equations (in MATLAB syntax for example) automatically?
There is no utility in MATLAB/Simulink that can do exactly what you are looking for (and I personally don't know of any third-party tools that can do this, either).
However, I think that your best bet might be to make use of Simulink Coder. This will allow you to convert your Simulink model to C code. From that code, you may be able to extract the equivalent equations more easily than you can by analyzing the Simulink model by hand.
The catch, though, is that Simulink Coder is an add-on package to base Simulink, so you may or may not have this tool available to you.
Does anybody know what components in Simulink (MATLAB package) are analogs for AnyLogic components? (e.g: source, buffer, delay, sink).
Or how can I easily simulate behavior of AnyLogic model in MATLAB?
Maybe there are some cool magic tools?
If you're asking whether or not there is an easy way to convert from an AnyLogic model to a Simulink model, I doubt it. I haven't seen any conversion tools like that.
I have a feeling you're just going to have to rebuild your AnyLogic model in Simulink if you want to simulate your models in MATLAB. I would start by looking through the Block List and Function List links on this Simulink documentation page. You should be able to find analogous components to those in your AnyLogic model.
AnyLogic is one of the best tools for business simulation and Matlab is the best engineering tool. But they have different notations.So in the most cases conversion is just impossible! E.g. to convert DE model of airport into Matlab.
My suggestion: use Matlab for engineering tasks and AnyLogic for business simulation.
