NETCDF error in MATLAB 2023b

Hi All,

I am using MATLAB 2023b trial version and can not work with NETCDF files.

In this case I am not able to simply read one netcdf file. What is going on?

Did I miss any matlab installation file? Is it a bug version? See below

the error I get:

>> test

Error using mexcdf

## Unrecognized Matlab version.

Error in ncread (line 46)

[ncid]=mexcdf('ncopen',fname,'nc_nowrite');

Error in netcdf_load (line 15)

val = ncread(ncfile,varname);

Error in test (line 3)

netcdf_load('swa12_2_grd.nc');

>>

Thanks for any help,

Luciano

odd. Question:are you using Apple Silicon?

[Luciano Pezzi]

I am using Macbook and IMac (with Sonoma 14.0 OS), and the error is the same in both machines.

I also face the same problem as yours in 2023b version on Windows 11.

Have you solved your error yet?

edit ncmex.m from line 113:

% Mex-file gateway.

v = version;

if eval(v(1)) > 4

fcn = 'mexcdf53'; % Matlab-5 or 6.

elseif eval(v(1)) == 4

fcn = 'mexcdf4'; % Matlab-4 only.

elseif eval(v(1:2)) >20

fcn = 'mexcdf60'; %Matlab-2020 or later.

else

error(' ## Unrecognized Matlab version.')

end
