I meet the same problem with the same environment. After I change the default setting to nonrecursive, the problem still exists. Although the hint change, the problem seems unchanged.

I meet the same problem with the same environment. After I change the default setting to nonrecursive, the problem still exists. Although the hint change, the problem seems unchanged.
Error Message below:
Error using vl_argparse (line 108)
Expected either a param-value pair or a structure.

Error in run_DCFNet>DCFNet_initialize (line 54)
state = vl_argparse(state, param, 'nonrecursive');

Error in run_DCFNet (line 27)
[state, ~] = DCFNet_initialize(im{1}, init_rect, param);

Error in demo_DCFNet (line 15)
res = run_DCFNet(subS,0,0,param);

It seems like the param must be a structure. If not, the function will be in loop. But I do not allow it to loop, the function have to stop because of the lack of structured parameter. Can you help me?
Thanks a lot.
