cdflib.getAttrMaxgEntry - Number of last entry for global attribute

Syntax

maxEntry = cdflib.getAttrMaxgEntry(cdfId,attrNum)

Description

maxEntry = cdflib.getAttrMaxgEntry(cdfId,attrNum) returns the last entry number of a global attribute in a Common Data Format (CDF) file.

Input Arguments

cdfId

Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.

attrNum

Numeric value that identifies the attribute. Attribute numbers are zero-based. The attribute must have global scope.

Output Arguments

maxEntry

Entry number of the last entry in the attribute. Entry numbers are zero-based.

Examples

Open the example CDF and get the number of the last entry associated with a global attribute in the file:

cdfid = cdflib.open('example.cdf');

% Any of the first three attribute are of global scope.
attrscope = cdflib.getAttrScope(cdfid,0)

attrscope =

GLOBAL_SCOPE


% Get the number of the last entry for this attribute.
entrynum = cdflib.getAttrMaxgEntry(cdfid,0)

entrynum =

     4

% Clean up
cdflib.close(cdfid);

clear cdfid
