Number of entries for attribute with global scope
nentries = cdflib.getNumAttrgEntries(cdfId,attrNum)
nentries = cdflib.getNumAttrgEntries(cdfId,attrNum)
returns the number of entries written for the specified global attribute
in the Common Data Format (CDF) file.
cdfId identifies the CDF file. attrNum is
a numeric value that identifies the attribute. Attribute numbers are
zero-based. The attribute must have global scope.
Open the example CDF and find out how many entries are associated with a global attribute in the file.
cdfid = cdflib.open('example.cdf');
% The first attribute is a global attribute.
attrgEntries = cdflib.getNumAttrgEntries(cdfid,0)
attrgEntries =
3
% Clean up
cdflib.close(cdfid);
clear cdfidThis function corresponds to the CDF library C API routine CDFgetNumAttrgEntries.
To use this function, you must be familiar with the CDF C
interface. Read the CDF documentation at the CDF website.
