Class Method Details

.new(n) ⇒ Object

allocate instance of WaveletWorkspace class.

This function allocates a workspace for the discrete wavelet transform. To perform a one-dimensional transform on n elements, a workspace of size n must be provided. For two-dimensional transforms of n-by-n matrices it is sufficient to allocate a workspace of size n, since the transform operates on individual rows and columns. A null pointer is returned if insufficient memory is available.

Parameters:

  • n (Integer) —

    parameter
