cdflib.setVarPadValue

Specify pad value used with variable

Syntax

cdflib.setVarPadValue(cdfId,varNum,padvalue)

Description

cdflib.setVarPadValue(cdfId,varNum,padvalue) specifies the pad value used with a variable in a Common Data Format (CDF) file.

Input Arguments

cdfId

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

varNum

Numeric value identifying a variable in the file. Variable numbers are zero-based.

padValue

Value to use a pad value for the variable. The data type of the pad value must match the data type of the variable.

Examples

Create a CDF, create a variable in the CDF, and then set the pad value used with the variable. To run this example, you must be in a writable folder.

cdfid = cdflib.create('your_file.cdf');

% Create a variable in the file.
varNum = cdflib.createVar(cdfid,'Time','cdf_int1',1,[],true,[]);

% Get the current pad value used with the variable 
padval = cdflib.getVarPadValue(cdfid,varNum)

padval =

    0

% Change the pad value for the variable
cdflib.setVarPadValue(cdfid,varNum,int8(1));

% Check the new pad value.
padval = cdflib.getVarPadValue(cdfid,varNum)

padval =

    1

%  Clean up
cdflib.delete(cdfid)

clear cdfid
