Detailed Description

Functor for the CONST projector.

Usage

    const(C): returns a CONST projector (functor), C defines the constant matrix to which the ouptut matrix of projector must be equal (before normalization).
    const(C,'normalized', bool,'pos', bool): the optional parameters are set. By default both normalized and pos are false.

Parameters

'normalized',true	normalizes the projection image according to its Frobenius norm.
'normalized',false	(the default) no normalization.
'pos',true	skips the negative values (replaced by zero) of the input matrix.
'pos',false	(the default) negative values are not skipped.

Return values

p	the const projector.
