  • Additional comments:

Example Python code to convert IQ data to MATLAB:

import numpy as np
import scipy.io as io

fname_prefix = "VEGAM20180313HR2U0C0S0FM_"
start_index = 240
stop_index = 240
for i in np.arange(start_index,stop_index+1,1):
    print("Converting: ",(fname_prefix+str(i)+".npy"))    
    x = np.load(fname_prefix+str(i)+".npy") # Load numpy array
    io.savemat((fname_prefix+str(i)+".mat"),dict(x=x)) # Save to matlab file
