Signal Toolkit - hilbert

Function File: h = hilbert (f, N, dim)

Analytic extension of real valued signal.

h = hilbert (f) computes the extension of the real valued signal f to an analytic signal. If f is a matrix, the transformation is applied to each column. For N-D arrays, the transformation is applied to the first non-singleton dimension.

real (h) contains the original signal f. imag (h) contains the Hilbert transform of f.

hilbert (f, N) does the same using a length N Hilbert transform. The result will also have length N.

hilbert (f, [], dim) or hilbert (f, N, dim) does the same along dimension dim.
