How to deal with name/value pairs of function arguments in MATLAB
- by Richie Cotton
I have a function that takes optional arguments as name/value pairs.
function example(varargin)
% Lots of set up stuff
vargs = varargin;
nargs = length(vargs);
names = vargs(1:2:nargs);
values = vargs(2:2:nargs);
validnames = {'foo', 'bar', 'baz'};
for name = names
validatestring(name{:}, validnames);
end
% Do something ...
foo = strmatch('foo', names);
disp(values(foo))
end
example('foo', 1:10, 'bar', 'qwerty')
It seems that there is a lot of effort involved in extracting the appropriate values (and it still isn't particularly robust again badly specified inputs). Is there a better way of handling these name/value pairs? Are there any helper functions that come with MATLAB to assist?
