The index of the matrix problem occurs because your file doesn't have 2*Fs = 16000 samples in it (<2 seconds). I noticed other problems as well, like the error is divided with the number of samples, and the read wav file isn't necessarily sampled with 8kHz.
Uploaded a fixed implementation based on this one. After it has been reviewed you should be able to find it on this site.
