Maximum written record number for variable


maxrec = cdflib.getVarMaxwrittenRecNum(cdfId,varNum)


maxrec = cdflib.getVarMaxwrittenRecNum(cdfId,varNum) returns the record number of the maximum record written 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 and record numbers are zero-based.


Open the example CDF, and then determine the maximum number of records written to a variable:

cdfid ='example.cdf');

% Determine the number records written to variable. 
numRecs = cdflib.getVarNumRecsWritten(cdfid,0)

numRecs =


% Determine the maximum record number of the records written
maxRecNum = cdflib.getVarMaxWrittenRecNum(cdfid,0)

maxRecNum =


%  Clean up

clear cdfid


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

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