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 = cdflib.open('example.cdf');
% Determine the number of records written to the variable.
numRecs = cdflib.getVarNumRecsWritten(cdfid,0)
numRecs =
24
% Clean up
cdflib.close(cdfid)
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.
