Write single value to variable

Syntax

cdflib.putVarData(cdfId,varNum,recNum,indices,datum)

Description

cdflib.putVarData(cdfId,varNum,recNum,indices,datum) writes a single value to a variable in a Common Data File (CDF) file.

Input Arguments

cdfId

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

varNum

Numeric value that identifies the variable to which you want to write the datum. Variable numbers are zero-based.

recNum

Numeric value that identifies the record to which you want to write the datum. Record numbers are zero-based.

dims

Dimension indices within the record. Dimension indices are zero-based.

datum

Data to be written to the variable.

Examples

Create a CDF, create a variable in the CDF and write data to the variable. To run this example, you must have write permission in the current folder.

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

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

% Write some data to the variable
cdflib.putVarData(cdfid,varNum,0,[],int8(98))

% Read the value from the variable.
datum = cdflib.getVarData(cdfid,varNum,0)

datum =

   98

%Clean up
cdflib.delete(cdfid);
clear cdfid
