cdflib.deleteVar(cdfId,varNum) deletes a variable from a Common Data Format (CDF) file.
cdfId identifies the CDF file. varNum is a numeric value that specifies the variable. Variable numbers are zero-based.
Create a CDF, create a variable in the CDF, and then delete it.
cdfid = cdflib.create('mycdf.cdf'); % Initially the file contains no variables. info = cdflib.inquire(cdfid) info = encoding: 'IBMPC_ENCODING' majority: 'ROW_MAJOR' maxRec: -1 numVars: 0 numvAttrs: 0 numgAttrs: 0 % Create a variable in the CDF. varNum = cdflib.createVar(cdfid,'Time','cdf_int1',1,,true,); % Retrieve info about the variable in the CDF. info = cdflib.inquireVar(cdfid, 0) info = name: 'Time' datatype: 'cdf_int1' numElements: 1 dims:  recVariance: 1 dimVariance:  % Delete the variable from the CDF cdflib.deleteVar(cdfid,0); % Check to see if the variable was deleted from the CDF. info = cdflib.inquire(cdfid) info = encoding: 'IBMPC_ENCODING' majority: 'ROW_MAJOR' maxRec: -1 numVars: 0 numvAttrs: 0 numgAttrs: 0 % Clean up cdflib.delete(cdfid); clear cdfid
This function corresponds to the CDF library C API routine CDFdeletezVar.
To use this function, you must be familiar with the CDF C interface. Read the CDF documentation at the CDF Web site.
