Detailed Description

The simplified parameterization class for factorizing a Hadamard matrix with the hierarchical factorization algorithm.

This type of parameters is typically used for a Hadamard matrix factorization. This is a variant of ParamsHierarchicalWHT. Here the intermediate residual factors are not constrained at all, the other factors are constrained with matfaust.proj.skperm.

Constructor & Destructor Documentation

ParamsHierarchicalWHTNoResCons()

function matfaust::factparams::ParamsHierarchicalWHTNoResCons::ParamsHierarchicalWHTNoResCons	(	n	,
		varargin
	)

Parameters

n	the number of output factors (the input matrix to factorize must be of size [2^n, 2^n]) .

Example

>> import matfaust.wht
>> import matfaust.factparams.*
>> import matfaust.fact.hierarchical
>> H = full(wht(32));
>> p = ParamsHierarchicalWHTNoResCons(5);
>> F = hierarchical(H, p);
