How to use GPU Coder and how to better write the main function

I was recently studying GPU coder to generate executables. I wrote a simple code photo.m, after generate, I did not send any valid code after the MATLAB conversion in photo.cu. Although I haven't changed the main function,such ashttps://ww2.mathworks.cn/help/coder/nvidia/ug/build-run-on-nvidia-hardware.html, this seems to have no effect on the photo.cu file.

So was my code converted successfully? Or not?

The functions that you are using (e.g. plot) are not supported for code generation. This isn't a limitation for GPU Coder specifically, but MATLAB Coder in general. Since these function calls do not have any effect on the output(s) computed by your application, they are omitted when generating standalone code. However, when generating a MEX instead, you can still generate extrinsic calls to these functions. Please see the link below for more information:
