"errors occurred during parsing of MATLAB function"

"errors occurred during parsing of MATLAB function" THis error i got while using matlab function (user defined function) with anonymous function.

[KSSV]

Show us the function...I guess you missed some grammatical syn taxes.

[Zahid Khan]

Its attached here attachment. In this code, RL1, QL1 , RL2 and QL2 are considered as input variables and v1r,v1q,v2r as output variables. This code workes on m.file. but i want to run it on matlab function (user defined function in sumulink).

Pleae help me out. hankx in advance.

@Zahid, have you checked the file which I have attached in the comment below???

[Zahid Khan]

@ammer Hamza , Sir, Actually you sent me file in 2018a version and my matlab is 2016a version, it was error while opring slx file. Now i downloaded 2018a version and installing that. After installation i will check it and reply you.

@Ameer Hamza Its working. I'm so much happy. and thank you very much bro. I spent considerable time but failed. and u did it.

[Ameer Hamza]

You are welcome.

You are getting these errors because MATLAB does not support code generation for all the function. The supported function list is here. Also, there are several restrictions for code generation for function handle. The easiest way to solve this problem is to move all of your code from Simulink function block to a MATLAB function file and save it in MATLAB path. Then define these functions as extrensic as shown on this link: https://www.mathworks.com/help/simulink/ug/calling-matlab-functions.html. Simulink will not try to generate code for the extrensic functions and simulation will run.

Yes, you are right. but i tried it on Matlab function it also give same error. I'm new in coding. Should i send you my code on your email address? I'm hope you can help me.. or may be u can send a blank email to me on '[e-mail]' then i will send it ..

It is better that you share your Simulink model file here. Other might contribute to the solution and the answer might be useful for some other people searching for the same problem. You can attach compress your model in a .zip file and upload it by using paperclip button.

But supouse with need to generate the code any way. How could we know wich function is causing problems?. Do we need to go one by one checking on the list?, or there is a smarter way?

Take a look at this section in the documentation for MATLAB Coder.

My errors and matlab function code are given in attached picture.

[Ameer Hamza]

@Zahid, it is better to add these images to your question instead of adding a new answer. You can delete this answer after adding these images to your question. Also, your error message in the image differs from the title. My answer addresses the errors shown in the image.

Kindly find attachment. In this code, RL1, QL1 , RL2 and QL2 are considered as input variables and v1r,v1q,v2r as output variables. This code workes on m.file. but i want to run it on matlab function (user defined function in sumulink).

It will be great honor if u help me to solve this problem as it is part of my project. Thankx in advance.

[Ameer Hamza]

Refer to the attached file. You can see how to define the function as extrinsic.

[Ameer Hamza]

Try this file for R2016a.

[Zahid Khan]

Sir, great love and respect for you. i tried older code as i installed 2018a. it working.

Hi there, i also have the same problem, but I do not know how to figure it out in order to correct it.

Could you please help me out?

I attached three screenshots in the pdf file.
