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 demo_im2mcg (line 10)

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,
