cdflib.getVarAllocRecords

Number of records allocated for variable

Syntax

numrecs = cdflib.getVarAllocRecords(cdfId, varNum)


Description

numrecs = cdflib.getVarAllocRecords(cdfId, varNum) returns the number of records allocated for a variable in a Common Data Format (CDF) file.

cdfId identifies the CDF file. varNum is a numeric value that identifies the variable. Variable numbers are zero-based.

Examples

Open example CDF and get the number of records allocated for a variable:

cdfid = cdflib.open('example.cdf');

% Determine the number of records allocated for the 
% first variable in the file.
numrecs = cdflib.getVarAllocRecords(cdfid,0)

numrecs =

    64


%  Clean up
cdflib.close(cdfid)

clear cdfid
