pyproximal.Hankel

class pyproximal.Hankel(dim: Tuple[int, ...])[source]

Hankel proximal operator.

Proximal operator of the Hankel matrix indicator function.

Parameters:
dimtuple

Dimension of the Hankel matrix.

Notes

As the Hankel Operator is an indicator function, the proximal operator corresponds to its orthogonal projection (see pyproximal.projection.HankelProj for details).
