cdflib.getAttrScope

Scope of attribute

Syntax

scope = cdflib.getAttrScope(cdfId,attrNum)


Description

scope = cdflib.getAttrScope(cdfId,attrNum) returns the scope of an 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 specifies the attribute. Attribute numbers are zero-based.

Output Arguments

scope

One of the following character vectors, or its numeric equivalent. Value Description 'GLOBAL_SCOPE' Attribute applies to the CDF as a whole. 'VARIABLE_SCOPE' Attribute applies only to the variable. To get the numeric equivalent of these constants, use the cdflib.getConstantValue function.

Examples

Open example CDF and get the scope of the first attribute in the file:

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

attrScope = cdflib.getAttrScope(cdfId,0)

attrScope =

    'GLOBAL_SCOPE'

% Clean up
cdflib.close(cdfId)
clear cdfId
