cdflib.getVarMaxWrittenRecNum - Maximum written record number for variable

Syntax

Description

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.

Examples

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

cdfid = cdflib.open('example.cdf');

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

numRecs =

    24


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

maxRecNum =

    23

%  Clean up
cdflib.close(cdfid)

clear cdfid
