wavelet.normalize(data)
Data normalize by variance. The mean value is removed.
Parameters: data: array_like Raw of data
Returns:
- data: array_like
Raw of data normalized
variance: Data variance
Notes
You can skip this function if it the normalization is not necessary (e.g. EOF data).
Example:
>> dt = 0.25
>> date1 = 1871
# Test data = sst_nino3.dat is already in the package!
>> data,n,time = load_txt('sst_nino3.dat',dt,date1)
# This normalize by variance
>> data_norm, variance = normalize(data)
