cdflib.getAttrMaxEntry

Number of last entry for variable attribute

Syntax

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.

`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 variable 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 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)
clear cdfId
