% Adds variables (with data) to a NETCDF file with handle "nc" |
| 6 |
% nc is the netcdf file handle |
| 7 |
% shortName is the name used to refer to the variable 'theta' |
| 8 |
% longName is a more descriptive name e.g. 'Potential temperature' |
| 9 |
% units is the units of the variable e.g. 'Degrees Celsius' |
| 10 |
% grid is a collection cell array of dimensino names e.g. {'Y' 'X'} |
| 11 |
% var is the scalar/vector/array of data to be written |
| 12 |
% record_number is the record slot to write when there is a "recordable" |
| 13 |
% dimension in the grid specification |
| 14 |
% |
| 15 |
% If "shortName" is identical to "grid" then the variable is written to the |
| 16 |
% netcdf file as dimension data and can subsequently be used in other grid |
| 17 |
% specifications. The size of the dimension is the length of the vector of |
| 18 |
% data. To create a recordable dimension, supply an empty vector, []. |
