Number of records allocated for variable


numrecs = cdflib.getVarAllocRecords(cdfId, varNum)


numrecs = cdflib.getVarAllocRecords(cdfId, varNum) returns the number of records allocated for a variable in a Common Data Format (CDF) file.

cdfId identifies the CDF file. varNum is a numeric value that identifies the variable. Variable numbers are zero-based.


Open example CDF and get the number of records allocated for a variable:

cdfid ='example.cdf');

% Determine the number of records allocated for the 
% first variable in the file.
numrecs = cdflib.getVarAllocRecords(cdfid,0)

numrecs =


%  Clean up

This function corresponds to the CDF library C API routine CDFgetzVarAllocRecords.

To use this function, you must be familiar with the CDF C interface. Read the CDF documentation at the CDF website.
