Question

I’m designing a function that takes as argument one structure and any number of flags. The function will contain a couple of ifs checking whether a specific flag is set.

What is the neatest way to achieve this? I was thinking about passing the flags as separate string arguments. Is there a neater solution?

Answer 1

I would do it like using varargin and ismember:

function foo(arg1,arg2,varargin)

  flag1=ismember('flag1',varargin);
  flag2=ismember('flag2',varargin);
  flag3=ismember('flag3',varargin);

And you can call the function like that:

foo(a1,a2,'flag3','flag1')

This will activate flag1 and flag3.
