cdflib.getVarNum

Variable number, given variable name

Syntax

varNum = cdflib.getVarNum(cdfId,varname)

varNum = cdflib.getVarNum(cdfId,varname) returns the identifier (variable number) for a variable in a Common Data Format (CDF) file.

cdfId identifies the CDF file. varname is a character vector or string scalar that identifies the variable. Variable names are case-sensitive.

Open example CDF, and then get the number of a variable named Longitude:

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

varNum = cdflib.getVarNum(cdfid,'Longitude')

varNum =

     1

%  Clean up
cdflib.close(cdfid);

clear cdfid
