Information about compression used by variable
[ctype,cparams,percent] = cdflib.getVarCompression(cdfId,
varNum)
[ctype,cparams,percent] = cdflib.getVarCompression(cdfId,
varNum) returns information about the compression used
for a variable in a Common Data Format (CDF) File.
|
Identifier of a CDF file, returned by a call to |
|
Character vector identifying the type of compression. For a
list of compression types, see |
|
Any additional parameter required by the compression type. |
|
Numeric value indicating the level of compression, expressed as a percentage. |
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 cdfidThis function corresponds to the CDF library C API routine CDFgetzVarCompression.
To use this function, you must be familiar with the CDF C
interface. Read the CDF documentation at the CDF website.
