Information about variable
info = cdflib.inquireVar(cdfId,varNum)
info = cdflib.inquireVar(cdfId,varNum) returns information about a variable in a Common Data Format (CDF) file.
Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.
Numeric value that identifies the variable. Variable numbers are zero-based.
Structure containing the following fields.
Record and dimension variances affect how the library physically stores variable data. For example, if a variable has a record variance of VARY, the library physically stores each record. If the record variance is NOVARY, the library only stores one record.
Open the example CDF file and get information about a variable.
cdfid = cdflib.open('example.cdf'); % Determine if the file contains variables info = cdflib.inquireVar(cdfid,1) info = name: 'Longitude' datatype: 'cdf_int1' numElements: 1 dims: [2 2] recVariance: 0 dimVariance: [1 0]
This function corresponds to the CDF library C API routine CDFinquirezVar.
To use this function, you must be familiar with the CDF C interface. Read the CDF documentation at the CDF Web site.
