Can i give mathworks a tip on the development of MATLAB?

Many languages have very convenient places, such as python, C / C + + allows custom function parameters default assignment operation, but matlab is "varargin, nargin, inputParser" to control the default assignment operation, more trouble, can be in the new version Add a default function input parameter like python?

for example:

function result = myAdd(a,b,c=1)
result = a+b+c
end

a and b is required param, c is optional param,can matlab new versin add this?

You can suggest whatever you want to mathworks via a service request. Whether or not, they act on it is another matter.

For your particular suggestion, you're in luck this has just been added to R2019b via the arguments block. Not exactly the same syntax as your suggestion, but more flexible anyway:

%R2019b only
function result = myAdd(a, b, c)
    arguments
        c (1, 1) double = 1
    end
    result = a+b+c;
end

R2021a add "Name=Value Syntax",but it still not perfect
