我喜欢使用结构为我的选择。这给你一个简单的方法来存储选项和一个简单的方法来定义它们。此外，整个事情变得相当紧凑。
function example(varargin)
%# define defaults at the beginning of the code so that you do not need to
%# scroll way down in case you want to change something or if the help is
%# incomplete
options = struct('firstparameter',1,'secondparameter',magic(3));
%# read the acceptable names
optionNames = fieldnames(options);
%# count arguments
nArgs = length(varargin);
if round(nArgs/2)~=nArgs/2
error('EXAMPLE needs propertyName/propertyValue pairs')
end
for pair = reshape(varargin,2,[]) %# pair is {propName;propValue}
inpName = lower(pair{1}); %# make case insensitive
if any(strcmp(inpName,optionNames))
%# overwrite options. If you want you can test for the right class here
%# Also, if you find out that there is an option you keep getting wrong,
%# you can use "if strcmp(inpName,'problemOption'),testMore,end"-statements
options.(inpName) = pair{2};
else
error('%s is not a recognized parameter name',inpName)
end
end
)
