static function	parse_opt_args (cell_args, opt_arg_names, opt_arg_map)
static function	get_constraints (constraints)
	Returns a cell array of constraints from constraints which is a ConstraintList or cell array that can be a mix of pyfaust.factparams.ConstraintGeneric or pyfaust.proj.proj_gen. If projs is a ConstraintList then the function just returns the same object as is. More...

Detailed Description

This class is a simple parameterization of PALM4MSA to factorize a Hadamard matrix using the matfaust.proj.skperm proximity operator.

Examples

import matfaust.factparams.ParamsPalm4msaWHT
import matfaust.fact.palm4msa
import matfaust.wht
d = 128;
H = full(wht(d));
p = ParamsPalm4msaWHT(d);
F = palm4msa(H, p);
err = norm(full(F)-H)/norm(H) % should be about 1e-16
