Is there anything faster than the below specified Matlab structure?

Dear all,

This is what I have as a matlab structure:

I first specify the following general function

function  [KK1, KK2]= fun_1(x,y1, y2)
........
end

Then I specify

target.posterior = @fun_1; 
target.inargs{1} = y1;    
target.inargs{2} = y2; 

And finally I include fun_1 in the following function

[KK3,KK4] = mel(x, target, ....);
    .....
    end

Is there any equivalent Matlab structure that could beat in speed the above structure in terms of how to imput the function fun_1 into the mel function?

Thanks a lot in advance!!

I use MatlabR2022a

This would be slightly better,

target.posterior = @fun_1; 
target.inargs = {y1,y2};

but you are down in the weeds. None of the operations in your post could ever be slow enough to be worth optimizing.
