带有句柄类的Matlab Arrayfun

Question

Say I have a 1x2 object array of a handle class with a method SetProperty. Can I use arrayfun to call the SetProperty method for each class, along with a vector for it to use to set the property value?

Answer 1

You can also design the class so that the call to SetProperty will be vectorized:

 class Foo < handle
      methods(Access=public)
            function SetProperty(this,val)
                 assert(numel(this)==numel(val));
                 for i=1:numel(this)
                      this(i).prop = val(i);
                 end
            end
      end
end

Then, you can create a vector and call the method on it directly:

    f = repmat(Foo(),[1 2]);
    f.SetProperty( [5 3]);

Answer 2

是的你可以：

arrayfun(@(x,y)x.SetProperty(y), yourHandleObjects, theValues)
