Hi ding barry,
I understand that you are encountering an error while generating CUDA code for the 'mandelbrot_count' function using GPU Coder.
The cause of the error was incorrect code generation configuration settings. To generate the code without any errors, follow the steps below.
- Create a GPU code generation configuration object.
% For mex
cfg = coder.gpuConfig('MEX');
% For static library
cfg = coder.gpuConfig('LIB');
% For Dynamic Linked library
cfg = coder.gpuConfig('DLL');
% For executable
cfg = coder.gpuConfig('EXE');
- Enable or disable required libraries.
% set the value to 'false' to disable
% Enabling Nvidia cuFFT
cfg.GpuConfig.EnableCUFFT = true;
% Enabling Nvida cuBLAS
cfg.GpuConfig.EnableCUBLAS = true;
- Set the required Compiler flags,
% For example
cfg.GpuConfig.CompilerFlags = '--fmad=false';
- Generate the code using ‘codegen’ command
% arg1, arg2 … are the arguments
codegen mandelbrot_count -args {arg1,arg2,arg3} -nargout 1
- You change the configuration settings of code generation in the app itself. In the ‘Check for Run-Time Issues’ screen, on the top right, you can find the ‘settings’ option
- In the settings select GPU Code section, in which you can change the configuration settings.
