If you have access to Python, the easiest thing would be to create a Python script such as the one below, and run that. It will find all .npz files in the current directory and convert that to .mat.
from scipy.io import savemat
import numpy as np
import glob
import os
npzFiles = glob.glob("*.npz")
for f in npzFiles:
fm = os.path.splitext(f)[0]+'.mat'
d = np.load(f)
savemat(fm, d)
print('generated ', fm, 'from', f)

Hello Juan,
I don't believe that either of those file formats are natively supported in MATLAB, but you can always check File Exchange to see if anyone has written an importer for them. A quick search did not turn up anything for NPY, but LVM turned up this one. If you have any questions about that File Exchange package, it's best to direct them to the author of the package.
