SORRY, I DO NOT MAINTAIN THIS ANY MORE BUT LEAVE IT ON FILE EXCHANGE AS IS.
I switched to python.
Reads Y-t data from binary files written by Yokogawa DL1600 series, DL750 or 7440 oscilloscopes.
hdrread.m reads the information from the *.hdr header files.
wvfread.m reads the Y-t data from binary *.wvf files.
Probably, it also works for other Yokogawa oscilloscopes, but this has not been tested. Please let me know if it works or not with other models.
