I want to export my variabels to a single .nc file

Hello.

I have a set of variables that i want to export as one .nc file so that i can use the dataset later on. I have tried using the instructions listed in this thread but it keeps returning an error. I'll include my code and the variables that i use below. And sorry for the rudamentary code, I'm still new to matlab

clear
clc

%masukin waktu
waktu= ncread('FABMSAT.nc','time');
waktu= waktu';

%masukin fito layer 1
fito= ncread('FABMSAT.nc','npzd_phy');
fito= fito(:,1,:);

%masukin pasut
pasut= ncread('FABMSAT.nc','zeta');

% masukin vector u
u= ncread('FABMSAT.nc','u');
u= u(:,1,:);

%Masukin vector v
v= ncread('FABMSAT.nc','u');
v= v(:,1,:);

%CUT SUPAYA MULAI 1 FEB 2022
waktu_feb= waktu;
waktu_feb(:,[1:168])=[];
fito_feb= fito;
fito_feb(:,[1:168])=[];
pasut_feb= pasut;
pasut_feb([2:8307],:)=[];
u_feb= u;
u_feb(:,[1:168])=[];
v_feb= v;
v_feb(:,[1:168])=[];

%define dimensions
netcdf.setDefaultFormat('NC_FORMAT_CLASSIC');
ncid = netcdf.create('test.nc','NC_WRITE');
dimidfito = netcdf.defDim(ncid,'fito_feb',fito_feb);

%Define the name of variable
var_fito = netcdf.defVar(ncid, 'fito_feb','NC_FLOAT',[dimidfito]);

%variables into .nc file
netcdf.endDef(ncid);
netcdf.putVar(ncid,var_fito,fito_feb);
netcdf.close(ncid);

Hi Ima,

To export your variables into NetCDF files, you can utilize MATLAB's NetCDF capabilities. To write variables into ".nc" files, you can use :

>> ncwrite("myfile.nc", "variablename", value)

For more information on creating and merging NetCDF files, along with additional details, please refer to the resource linked below:

Hope this helps!
