Write data to NetCDF file
ncwrite(filename,varname,vardata)
ncwrite(filename,varname,vardata,start,stride)
ncwrite(filename,varname,vardata) writes
the numerical or char data in vardata to an existing
variable varname in the NetCDF file filename.
ncwrite writes the data in vardata starting
at the beginning of the variable and extends unlimited dimensions
automatically, if needed.
If the NetCDF file or the variable do not exist, use nccreate to
create them first.
ncwrite(filename,varname,vardata,start,stride) writes vardata to
an existing variable varname in file filename beginning
at the location given by start. stride is
an optional argument that specifies the inter-element spacing of the
data written. Use this syntax to append data to an existing variable
or write partial data.

Text string specifying the name of a NetCDF file. If the file
does not exist, use |

Text string specifying the name of a variable in a NetCDF file.
If the variable does not exist, use |

Data to write to the variable in the NetCDF file. |

For an N-dimensional variable, |

(Optional) Vector of length N, specifying the inter-element spacing. Default: Vector of ones |
Create a new netcdf4_classic file, and write
a scalar variable with no dimensions. Add the creation time as a global
attribute.
nccreate('myfile.nc','pi');
ncwrite('myfile.nc','pi',3.1);
ncwriteatt('myfile.nc','/','creation_time',datestr(now));
% overwrite existing data
ncwrite('myfile.nc','pi',3.1416);
ncdisp('myfile.nc');
Create a netcdf4_classic file with a variable
defined on an unlimited dimension. Write data incrementally to the
variable.
nccreate('myncfile.nc','vmark',...
'Dimensions', {'time', inf, 'cols', 6},...
'ChunkSize', [3 3],...
'DeflateLevel', 2);
ncwrite('myncfile.nc','vmark', eye(3),[1 1]);
varData = ncread('myncfile.nc','vmark');
disp(varData);
ncwrite('myncfile.nc','vmark',fliplr(eye(3)),[1 4]);
varData = ncread('myncfile.nc','vmark');
disp(varData);
