cdflib.getVarNumRecsWritten

Number of records written to variable

Syntax

numrecs = cdflib.getVarNumRecsWritten(cdfId,varNum)

Description

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.

Examples

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
