Number of records written to variable


numrecs = cdflib.getVarNumRecsWritten(cdfId,varNum)


numrecs = cdflib.getVarNumRecsWritten(cdfId,varNum) returns the total number of records written to 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 the example CDF, and then determine the number of records written to a variable:

cdfid ='example.cdf');

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

numRecs =

clear cdfid


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

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