Intermediate files for real data benchmark has 'nan' elements.

[jbjeong]

Hello, thank you for the great work.

I found the issue on intermediate files for real data benchmark on Geometric Registration on Synthetic Data
( intermediate-files-real.zip )

The data has 'nan' elements.
For example,
fid = fopen('cloud_bin_0.desc.3dmatch.bin', 'rb')
data = fread(fid, 'single')
num_points = data(1)
num_feats = data(2)
feat = data(3:end)

any(isnan(feat))
-> ans = 1
sum(isnan(feat))
-> ans = 512

Thanks.
