kwargify

Specify default values in your function. Pass a structure of variables that you wish to overwrite, and kwargify will update that. You can decide to overwrite some, all, or none of the values. You can also pass additional values.
It works by basically overwriting the fields of your default options structure with any that are specified in your charge structure.

Example usage

%% Example 1
% I want to call myFunction, but I just want to use the defaul options and not specify any kwargs
myFunction(42,[])

%% Example 2
% Now I want to overwrite the default value for b, and add an extra one d, so I will specify my kwargs here. You can call them opts though if you prefer.
kwargs.b = 5;
kwargs.d = 4;

% call myFunction with these kwargs
myFunction(42,kwargs)

myFunction is your function which will have the following general form:

function myFunction(exampleRequiredArgument,kwargs)
% If you want your function to work with kwargs, then you have to specify
% default options in a structure here. These will be overwritten by
% fieldnames in the kwargs structure. If kwargs are not provided (ie
% kwargs=[]) then the detaults are used.

% Default options
opts.a = 1;
opts.b = 2;
opts.c = 3;

% display the default opts
display('defaults are:'), opts

% This is where the magic happens ~~~
opts = kwargify(opts,kwargs);
% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

% display the updated opts
display('after using ''kwargify'': '), opts

% DO SOMETHING USEFUL HERE USING VALUES IN (opts) STRUCTURE
display(exampleRequiredArgument+ opts.b)
