FUNC_PARAMS
Name Data Type Description
WAVELET VARCHAR (128) Name of the wavelet. Option families and names are:
  • Daubechies: 'db1' or 'haar', 'db2', 'db3', .... ,'db38'
  • Coiflets: 'coif1', 'coif2', ... , 'coif17'
  • Symlets: 'sym2', 'sym3', ... ,' sym20'
  • Discrete Meyer: 'dmey'
  • Biorthogonal: 'bior1.1', 'bior1.3', 'bior1.5', 'bior2.2', 'bior2.4', 'bior2.6', 'bior2.8', 'bior3.1', 'bior3.3', 'bior3.5', 'bior3.7', 'bior3.9', 'bior4.4', 'bior5.5', 'bior6.8'
  • Reverse Biorthogonal: 'rbio1.1', 'rbio1.3', 'rbio1.5' 'rbio2.2', 'rbio2.4', 'rbio2.6', 'rbio2.8', 'rbio3.1', 'rbio3.3', 'rbio3.5', 'rbio3.7','rbio3.9', 'rbio4.4', 'rbio5.5', 'rbio6.8'
If this parameter is specified, then do not include a second input series for the function. If this parameter is not specified, then include a second input series to provide the filter.

Data type is case-sensitive.

MODE VARCHAR (128) Signal extension mode. Options are:
  • symmetric, sym, symh
  • reflect, symw
  • smooth, spd, sp1
  • constant, sp0
  • zero, zpd
  • periodic, ppd
  • periodization, per
  • antisymmetric, asym, asymh
  • antireflect, asymw

Data type is case-insensitive.

LEVEL Integer Level of decomposition. Valid values are [1,15]. Default is 1.
PART CHAR Indicator that partial decomposition result is needed. Valid values are ā€˜aā€™ or ā€˜dā€™, corresponding to the approximation or the detail of the decomposition result.

Data type is case-insensitive.
