Variable number, given variable name


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 that identifies the variable. Variable names are case-sensitive.

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

varNum =
