Extract_basic_features.m some puzzlement

[bwdeng20]

In this MATLAB function, the input variable x is always 1 by 128 thus n is identical to 1. As a sequence,
hist(x,10)/n == hist(x,10), leading to nondistinctive feature extraction for different segment size(I guess that's what u want to do).
Thx for your open source code. @aiff22
