gpu coder get wrong results in multiple functions with coder.varsize

The following code is an example, when I use gpu coder to compile to mex file, the result is only output = 0, rather than a required vector array, I do not know how to modify and find other related samples.

function output=main_test(input)
%#codegen
% Map computation to GPU.
coder.gpu.kernelfun;
output=0;
coder.varsize('output');
output = varfun(input, output);
end
function out_var = varfun(in_var, out_var)
for i=1:10    
    out_var = [out_var, in_var +2];
end
end

Hi Jibao,

Thanks for reporting the issue. Can you provide us more information list here to reproduce the issue?

1. MATLAB script for reproduction with input, codegen command or GPU Coder project file
2. MATLAB version
3. Operating system, Windows or Linux? Which version?
4. GPU device

Thanks,

Chao

Hi Chao, I use my friend's matlab software, the version is R2021b, the Operating system is Windows 10, the GPU device is NVIDIA Quadro k2200.

when I upgraded the matlab version to r2022b update3, the results is right.

Thanks!
