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

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.

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.

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?

@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.

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