cdflib.getAttrMaxgEntry

Number of last entry for global attribute

Syntax

maxEntry = cdflib.getAttrMaxgEntry(cdfId,attrNum)

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

`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.

maxEntry

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 a global attribute in the file:

cdfId = cdflib.open("example.cdf");

% All 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
