Importing Data from a CDF File
To import data into the MATLAB workspace from a CDF file, use the cdfread
function. Using this function, you can import all the data in the file, specific
variables, specific records, or subsets of the data in a specific variable. The
following examples illustrate some of these capabilities.
1 To get information about the contents of a CDF file, such as the names of
variables in the CDF file, use the cdfinfo function. In this example, the
Variables field indicates that the file contains five variables. The first
variable, Time, is made up of 24 records containing CDF epoch data. The
next two variables, Longitude and Latitude, have only one associated
record containing int8 data. For details about how to interpret the data
returned in the Variables field, see cdfinfo.
info = cdfinfo('example.cdf');
vars = info.Variables
