Netcdf on MATLAB 2023b

Hi,

Has anyone tried running CROCO with the MATLAB 2023b (trial) version? There’s a problem recognizing this matlab version when creating a netcdf file. It says “Unrecognized Matlab Version” in the file ‘create_grid.m’ Please let me know if you encountered this problem, and how you solved it. Thanks.

Hi,
Ansong

Indeed
Their are issues with MATLAB 2023b/R2024a_Prerelease due to comparability with netcdf_matlab_60. i will suggest you that you downgrade the matlab version. and run croco_tools. I can assure you that we will find some patch to fix this issues soon. or you can use GNU Octave (https://octave.org/).
start.m to oct_start.m
Cheers!

Hi,

To use GNU Octave you need an older version of Octave, e.g. v4.2.2, one that can load or compile the OctCDF package v 1.1.10

Hi,

Please try this in Octave to see if things work well

nc=netcdf(‘a.nc’,‘c’);
close(nc)
exit

and then in the shell
ncdump -h a.nc

you should get something like

netcdf a {
}
