Blocking factor for variable


blockingFactor = cdflib.getVarBlockingFactor(cdfId,varNum)


blockingFactor = cdflib.getVarBlockingFactor(cdfId,varNum) returns the blocking factor for a variable in a Common Data Format (CDF) file. A variable's blocking factor specifies the minimum number of records the library allocates when you write to an unallocated record.

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


Open the example CDF and determine the blocking factor of a variable.

cdfid ='example.cdf');


ans =


%  Clean up
clear cdfid


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

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