Hi all

I am using, read_grib.m file, to read the NCEP nww3 wind.grb files with the command,

grib_struct=read_grib('nww3.wind.199807.grb', -1)

To some extent it is reading I think, later, it is showing the following error:

Parameter Table set to NCEPOPER
Searching for first GRIB marker...
GRiB Record marker "GRIB" found at chars 1-4
GRiB header =
GRIB
GRec= 1 : FPos1= 4??? Undefined command/function 'BDS_unpack_mex5'.

Error in ==> read_grib.r3\private\extract_grib at 64
dataarray=BDS_unpack_mex5(bds_struct.bindata,...

Error in ==> read_grib at 301
[pds_struct,gds_struct,bms_struct,bds_struct,dataarray]=...

CAn anyone please help me.

Thanku & regards,
Neel
