Input Arguments

collapse all

Name of a NetCDF file, specified as a string. source also can be the URL of an OPeNDAP NetCDF data source that resolves to a NetCDF file or a variable in a NetCDF file.

Example: 'myNetCDFfile.nc'

Data Types: char

Location of a variable or group in the NetCDF file, specified as a string. Set location to '/'(forward slash) to display the entire contents of the file.

Data Types: char

Display format, specified as one of the following strings.

'full'Display group hierarchy with dimensions, attributes, and variable definitions.
'min'Display group hierarchy and variable definitions.

Data Types: char
