Read .GRIB2 files in Matlab

Hi, I am currently using a java toolbox (nc/nj varget) to read .grib2 files in Matlab. However, the files are a many and the process takes a lot of time. I was wondering if

a) is there a faster function in matlab to read .grib2 files? b) will converting them to another format will help?

I ve tried converting them to binary and reading them using fread and fread it is faster but I have to use wgrib2 to convert them in Linux first so its a lot of pre-processing.

Any feedback appreciated Thank you

As of R2023b, you can read data from a GRIB file (.grb, .grib, .grib2) using the Mapping Toolbox readgeoraster function. You can also get information about a GRIB file by using the georasterinfo function. These functions were enhanced in R2024b to support GRIB files that use CCSDS compression.
