cdflib.getVarRecordData

Entire record for variable

Syntax

data = cdflib.getVarRecordData(cdfId,varNum,recNum)

data = cdflib.getVarRecordData(cdfId,varNum,recNum) returns the data in a record associated with a variable in a Common Data Format (CDF) file.

cdfId

Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.

varNum

Numeric value that identifies the variable in the CDF file. Variable numbers are zero-based.

recNum

Numeric value that identifies the record in the variable. Record numbers are zero-based.

data

Data in the record.

Open the example CDF, and then get the data associated with a record in a variable:

cdfId = cdflib.open("example.cdf");

% Get data in first record in first variable in file
recData = cdflib.getVarRecordData(cdfId,0,0)

recData =

   6.3146e+13

% Clean up
cdflib.close(cdfId)
clear cdfId

This function corresponds to the CDF library C API routine CDFgetzVarRecordData.
To use this function, you must be familiar with the CDF C interface. You can access the CDF documentation at the CDF website.

You can read the record data of CDF_INT8 and CDF_TIME_TT2000 variables.
