Number of last entry for variable attribute
maxEntry = cdflib.getAttrMaxEntry(cdfId,attrNum)
maxEntry = cdflib.getAttrMaxEntry(cdfId,attrNum)
returns the number of the last entry for an attribute in a Common
Data Format (CDF) file.
cdfId identifies the CDF file.
attrNum is a numeric value that specifies
the attribute. Attribute numbers are zero-based. The attribute must
have variable scope.

Numeric value that identifies the attribute. Attribute numbers are zero-based. The attribute must have variable scope. |
|
Entry number of the last entry in the attribute. Entry numbers are zero-based. |
Open the example CDF and get the number of the last entry associated with an attribute with variable scope in the file:
cdfid = cdflib.open('example.cdf');
% The fourth attribute is of variable scope.
attrscope = cdflib.getAttrScope(cdfid,3)
attrscope =
VARIABLE_SCOPE
% Get the number of the last entry for this attribute.
entrynum = cdflib.getAttrMaxEntry(cdfid,3)
entrynum =
3
% Clean up
cdflib.close(cdfid);
