For the following, is there any robust way to set the class object properties at once by copying each input struct field value to its corresponding class object property wihtout iterating over them one-by-one?
classdef classX
properties
Prop1, Prop2, Prop3;
end
methods
function obj = classX(namedArgs)
arguments
namedArgs.Prop1 = default1;
namedArgs.Prop2 = default2;
namedArgs.Prop3 = default3;
end
% How to make the following lines robust and indepedent of the number of object properties?
obj.Prop1=namedArgs.Prop1;
obj.Prop2=namedArgs.Prop2;
obj.Prop3=namedArgs.Prop3;
end
end
end

One option might be something like this:
% How to make...
fnames = fieldnames(namedArgs);
for ifield=1:length(fnames)
s = fnames{ifield};
obj.(s) = namedArgs.(s);
end
