Specify range of records to be allocated for variable
cdflib.setVarAllocBlockRecords(cdfId,varNum,firstrec,lastrec)
cdflib.setVarAllocBlockRecords(cdfId,varNum,firstrec,lastrec)
specifies a range of records you want to allocate (but not write)
for a variable in a Common Data Format (CDF) file.
|
Identifier of a CDF file, returned by a call to |
|
Numeric value identifying a variable in the file. Variable identifiers (variable numbers) are zero-based. |
|
Numeric value identifying the record at which to start allocating. Record numbers are zero-based. |
|
Numeric value identifying the record at which to stop allocating. Record numbers are zero-based. |
Create a CDF, create a variable in the CDF, and then specify the number of records to allocate 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 allocate.
cdflib.setVarAllocBlockRecords(cdfid,varNum,1,10);
% Clean up
cdflib.delete(cdfid)
clear cdfidThis function corresponds to the CDF library C API routine CDFsetzVarAllocBlockRecords.
To use this function, you must be familiar with the CDF C
interface. Read the CDF documentation at the CDF website.
