matlab coder:Can the C++ functions generated for the entry point functions of the "arguments" validation syntax take mergeability into account?

For example, there is such an entry-point function in matlab that needs to generate C/C++ code, and I have generated several functions that are suitable for "different" types using the following command line, can these functions be merged into one for code simplicity and readability?

function out = useDefault(a,st)%#codegen
arguments
    a (1,1) double
    st (1,1) struct = struct("name","cuixing",...
        "score",100);
end

% Specify the class of the input as struct.
assert(isstruct(st)); % https://www.mathworks.com/help/coder/ug/define-input-properties-programmatically-in-the-matlab-file.html#bq_w7jz-1

% Specify the class and size of the fields.
% assert(isa(st.name,'string')); %https://www.mathworks.com/help/coder/ug/define-string-scalar-inputs.html
assert(isa(st.score,'double'));

out = a + st.score;
end

command line:

codegen -config:lib -c -args {1,struct('name',"zhang",'score',50)} -args {100} -args {20,struct('name',"ab",'score',20)} -report useDefault -lang:c++

Note: I have specified the input multiple times with the "-args" parameter to represent a wider range of input types.

The resulting C++ code then has multiple similar functions for each `-args`, which does not take advantage of the overloading feature in C++ or use the default argument feature inherent in C++, could this be improved?

Hi Cui,

Thanks for the inputs.

"Overloading feature" is unfortunately not supported in MATLAB Coder as of MATLAB 2022b. We've made an internal note of your request so we can look at lifting that limitation in the future.

Thank you also for your prompt and quick reply
