10.2) High Level Access: Reading
The arrays within a NetCDF file represent data as well as supporting attribute data.
Matlab has functions to read data and attributes. In its simplest form:
[matlab]
>> filename='data.nc'
>> ncdisp(filename);
>> data=ncread(filename, 'a');
>> a_info=ncreadatt(filename, 'a', 'description')
>>
[/matlab]
| Command | Description | Example | ncdisp | Display text description of the contents | ncdisp(filename) |
| ncinfo | Gets information about a file or field | finfo=ncinfo(filename)ncinfo(filename, var_name) |
| ncread | Reads data from a variable in a file | data=ncread(filename, var_name) |
| ncreadatt | Reads attribute data from a file | att_value=ncreadatt(filename, var_name, att_name) |
