Value of entry in attribute with variable scope
value = cdflib.getAttrEntry(cdfId,attrNum,entryNum)
value = cdflib.getAttrEntry(cdfId,attrNum,entryNum) returns the value of an attribute entry in a Common Data Format (CDF) file.
Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.
Numeric value that identifies the attribute. Attribute numbers are zero-based. The attribute must have variable scope.
Numeric value that specifies the entry in the attribute. Entry numbers are zero-based.
Open the example CDF and get the value of an 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 information about the first entry for this attribute [dtype numel] = cdflib.inquireAttrEntry(cdfid,3,0) dtype = cdf_char numel = 10 % Get the value of the entry for this attribute. % Note that it's a character string, 10 characters in length value = cdflib.getAttrEntry(cdfid,3,0) value = Time value % Clean up cdflib.close(cdfid); clear cdfid
