Syntax

Description

cdflib.setVarInitialRecs(cdfId,varNum,numrecs) specifies the initial number of records to write to a variable in a Common Data Format (CDF) file.

Input Arguments

Examples

Create a CDF, create a variable, and then specify the number of records to write for 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,'Grades','cdf_int1',1,[],true,[]);

% Specify the number of records to write for the variable
cdflib.setVarInitialRecs(cdfid,varNum,100);

recsWritten = cdflib.getVarNumRecsWritten(cdfid,varNum)

recsWritten =

   100

%  Clean up
cdflib.delete(cdfid)
