I was able run the file 'compile.m' successfully. However when I call the following function
c = cdi_varlist(filename,);
I get the following
error: cdi_varlist: No such file or directory
Although I'm pretty sure the file name and path is correct. I identified the error coming from the file cdi_mx.c at the following line
streamID = streamOpenRead(szInputFilename);
So basically 'streamOpenRead' cannot open my file although the path and the name are correct. I tried with and without the file extension (.grb). Also, no capabilities to read the contents of the file (e.g. \private\...) are actually required.
