WebTherefore, inverting Hilbert matrices is numerically unstable. When you compute a matrix inverse, H*inv (H) must return an identity matrix or a matrix close to the identity matrix within some error margin. First, compute the inverse of H by using the inv function. A warning is thrown due to the numerical instability. H*inv (H) WebTo compute the Hilbert transform, use htrans. The inverse Hilbert transform of a function is equal to the negative of its Hilbert transform. For a signal in the time domain, the inverse Hilbert transform applies a 90-degree phase shift to negative frequencies of the corresponding Fourier components.
