error happened when i runing the pre-trained/demo_im2mcg.m

[forrestsz]

i download the code in my ubuntu environment. i want to reproduce the segmentation result in paper, so i choose the pre-trained document first, i run install.m eveything is ok. then, i run the demo_im2mcg.m, something happend as following:

Error using eigs Too many output arguments.

Error in spectralPb_fast>ncuts2 (line 130) [EV, EVal, debug1, debug2] = eigs((D - A) + (10^-10) * speye(size(D)), D, n_ev, 'sm', opts);

Error in demo_im2mcg (line 10) [candidates_scg, ucm2_scg] = im2mcg(I,'fast');

it look like something wrong inside the eig function

thank you!

hello,i want to know how to run the code with my own dataset,could you give some suggesstion?Thank you!

Dear @linqinghong and @Alice-Shen, I am sorry but I cannot give this level of support for MCG anymore. It looks like Matlab might have changed the interface for the eig function, but I cannot tell for sure. Best,
