cdflib.getVarMaxWrittenRecNum

Maximum written record number for variable

Syntax

maxrec = cdflib.getVarMaxwrittenRecNum(cdfId,varNum)


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
