WebFunction Reference: 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.
