Computes the wavelet transform based on the Daubechies4 function of a sequence.
The input sequence.
The length of the sequence has to be a power of 2, otherwise this node returns an error.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
The wavelet Daubechies4 transform of the input sequence.
Error information. The node produces this output according to standard error behavior.
The Wavelet Transform Daubechies4 transform can be defined using the following transformation matrix:
The Wavelet Daubechies4 transform of an array X is defined by the following equation:
Where This Node Can Run:
Desktop OS: Windows
FPGA: Not supported
