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

Tips

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

• To use this function, you must be familiar with the CDF C interface. You can access the CDF documentation at the CDF website.
