Write grib files in MatLab

Hello,

I have a .grib file from ecmwf.int, containing selected ERA-interim data for the last 10 years. I downloaded this as one file as it would have taken forever to download each day individually. What I would like MatLab to do is to split this file up in individual days in a file system where we have folders for each year, containing folders for each month, and the .grib file we write from MatLab for each day should be saved in the correct year and month folders.

Can anyone help me with this?

There are many tools in the net which allow to download a set of files even if it contains many files. Installing and using one of these tools would be much more efficient than creating a Matlab function to split the files. But if you really want to do this in Matlab: Yes, anyone can help you to create this function. Simply ask a specific question. Show the exitsing code and explain the occurring problems. Include a description of the ".grib" files, because you cannot expect the readers to be familiar with this format.
