Method Detail
- daubTrans
```
public void daubTrans(double[] s)
```
  Forward wavelet transform
  
  Parameters:
  
  s - input vector
- invDaubTrans
```
public void invDaubTrans(double[] coef)
```
  Inverse wavelet transform
  
  Parameters:
  
  coef - input vector
- invoke
```
public double[] invoke(double[] input)
```
- invTransform
```
protected void invTransform(double[] a,
                            int n)
```
- transform
```
protected void transform(double[] a,
                         int n)
```
  Forward wavelet transform.
  
  Note that at the end of the computation the calculation wraps around to the beginning of the signal.
  
  Parameters:
  
  a - input signal, which will be replaced by its output transform
  
  n - length of the signal, and must be a power of 2
