Highlevel functions simplify the process of reading data from a netcdf file or writing a variable from the matlab workspace into a netcdf file. Time axis in netcdf files matlab answers matlab central. This matlab function returns the id of the child group, specified by the name childgroupname, in the file or group specified by ncid. This matlab function displays all the groups, dimensions, variable definitions, and all attributes in the netcdf data source, source, as text in the command window. Featool multiphysics matlab fem toolbox featool multiphysics is a fully integrated, flexible and easy to use physi. The chunksize parameter controls the spaceversustime tradeoff, memory that the netcdf.
This matlab function returns the compression parameters for the netcdf variable specified by varid in the location specified by ncid.
