cdflib.getVarCompression - Information about compression used by variable

Syntax

Description

[ctype,cparams,percent] = cdflib.getVarCompression(cdfId, varNum) returns information about the compression used for a variable in a Common Data Format (CDF) File.

Input Arguments

Output Arguments

Examples

Open the example CDF file and check the compression settings of any variable.

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

% Check the compression setting of any variable in the file
% The example checks the first variable (variable numbers are zero-based).
[ctype params percent] = cdflib.getVarCompression(cdfid,0)

ctype =

NO_COMPRESSION


params =

     []


percent =

   100

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