I have fix the problem by using vlfeat toolbox, http://www.vlfeat.org/index.html, vl_colsubset is a function of this toolbox.

hi @gyguo , can you give me the detail step on how you implement vlfeat toolbox. I have a problem like you and I think I have vlfeat toolbox on my computer.

Thank you.

@sudonto After download and install the vlfeat toolbox under the st-resnet directory, I add run(fullfile(fileparts(mfilename('fullpath')), ... 'vlfeat','toolbox', 'vl_setup.m')) ; to the STMulNet.m before runing it
