Hello Everyone,

I would like to perform the cross correlation function (crosscorr (y1,y2)) for my data but donot have the Econometrics Toolbox to compute this. Can someone in here help me to get this toolbox or else show me where I could get one?

many thanks, Tobias

Hello all,

I have created an arbitrary model for microtubule behavior. More or less just trying to familiarize with the software. I have created plots for multiple types of reactions that may occur and am looking to now plot the instantaneous derivative of each reaction. Would anyone have any suggestions as to how I could do this? I am familiar with how to do it with a clearly defined function with x,y,z,etc. values. However the 'sbiomodel' command doesn't seem to show me a function so I'm really lost on this.

Thanks for any and all help/suggestions.

Hi. I'm new to matlab. I'm a hobbyst, not a company or anything like this. I brought MATLAB personal with some modules and I'll use to learn FPGA with ZedBoard + AD9361. I know that this board (both) are supported by simulink and I'll test/learn using simulink and block-design. My plan is to make an FM transmitter (for start) when my boards arrive (already brought, still waiting delivery). After that, my plan is to make an receiver and then, do the same receiver, but using another frontend (including ADC). So my question is: imagine that I have plugged in another ADC into my ZedBoard (let's say AD9226), is possible to read this ADC in simulink, like AD9361 does? If yes, how? Where can I find any article or tutorial about this?

Even further: if I want to generate HDL code in the future (using HDL Coder), how can I integrate this 'custom' AD for code generation?

PS: I know that I can't buy HDL Coder for personal. My plan is to use trial for testing, since I'm using just for learning.

Thank you.

I am trying to design the outer voltage loop of the inverter but i am unable to remove the 5,7th harmonics from the capacitor voltage as i am trying to supply nonlinear load. The file is in matlab2018b.

Model-Based Design speeds up developing embedded software for controllers in power electronics-based systems. Wherever you plan to use digital controls, you can use Model-Based Design to develop, test, and implement your algorithms. You can learn more about Model-Based Design in this white paper .

Hello,

I have a suggestion for a feature which I think would be nice to add in SimBiology: a "date modified" field for all of the objects (species, parameters, rules, etc). It would be nice for this to be visible in the tables in the GUI, as well as being available through code, and to be able to sort on this field in the GUI. The reason I thought about this is because I just got a model with some updates from a colleague, and this would help me to identify what they updated.

Thank you,

Abed

In previous versions, there was an option for exporting fit results as a report. Now it is not there.

1.When I am trying to code my TMS320F28379D for running a three phase grid tied plant as per the attached image a scope in "SYNCHRONOUS SYSTEM " is showing perfect result but the result is not getting transferred to the "PI_Controller_ISR ".I have concluded this after I have connected the scope at the signal which is entering the "PI_Controller_ISR " subsystem (Inside the subsystem). I am trying to do this in MATLAB 2018B AND F28379D LAUNCHPAD.I am attaching the MATLAB fILE with this help request.Kindly resolve the issue. 2. I have been working on how to send the ADC signal from the C2000 MCU to the Host by seeing the video of** f28379D_DCDC_Buck** in external Mode, but when I downloaded the file and tried to run it by setting the parameters in the HARDWARE IMPLEMETATION pane it is showing me the error message. " Error evaluating 'InitFcn' callback of C28x SCI Receive block (mask) 'c28379Dpmsmfocdual_cpu1_ert/Serial Receive/SCI Receive'. Callback string is 'c28xsci_callback('renderDisplay') validateC280xSCI('Rx'); codertarget.registry.registerC280xSCIRxBlocks(gcb);

Kindly resolve these issues.

Please send me some plant digital twin simulink model for productive maintenance.

i want to model LI+ battery , i referred to matlab model https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/36019/versions/29/download/zip but not able to understand how to make simscape battery parametrs(like R C ), anybody can help ??

Hi, How to represent a transfer function (TF) of a compensated system in MATLAB to plot the bode plot of it, without expanding the denominator? The TF is: T(s) = (1 + s/Wz) / ( (1 + s/Wp) * ( 1 + s/Wo + s^2/W0^2 ) )

I am simulating the attached paper on modulated model predictive control. I have done everything as in the paper. Can some please tell me about my mistake? I am so frustrating since two weeks. Thanks&Regards, G.Sivakumar.

Over the past several months our communities have been the target of ongoing spam attacks. Spam is a common issue online and spam prevention is something we include as part of our standard development processes. The most recent attempts appear to be specifically targeting our sites with a combination of manual and automated attacks, probing with a variety of content attempting to bypass our filters. Regrettably, the attacks sometimes make it through our defenses, cluttering your inboxes and the content in our communities.

Rest assured, we are dedicated to continuing to evolve our tools and improve our capabilities to meet the goal of eliminating all spam in our communities. We appreciate your patience and understanding as we work to get there.
