Detailed Description

Functor for the CIRC projector.

The output matrix of the projector is a circulant matrix.

Each constant used to fill a pair of diagonals of the output matrix is the mean of all the input matrix entries that it replaces in the output matrix.

Usage

    circ(shape): returns a CIRC projector (functor), shape defines the size of the input matrix (e.g. [1, 10]).
    circ(shape,'normalized', bool,'pos', bool): the optional parameters are set. By default both normalized and pos are false.

Parameters
'normalized',truenormalizes the projection image according to its Frobenius norm.
'normalized',false(the default) no normalization.
'pos',trueskips the negative values (replaced by zero) of the input matrix.
'pos',false(the default) negative values are not skipped.
Return values
circprojector.
