Vl_feat installation error

while installing vl_setup, I am getting this warning:

Warning: Function cummax has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict. > In path (line 109) In addpath (line 88) In vl_setup (line 78) In run (line 96)

Thanks in advance
