%DESIGNOPTIONS Show all design options available for a particular design % S = DESIGNOPTIONS(D, METHOD) returns a structure, S, with all design % options available for an object D using a particular design method, % METHOD. % % S = DESIGNOPTIONS(D, METHOD, 'SystemObject', FLAG) limits the list of % filter structures to those that are supported by System objects when % FLAG is set to true. Lists all the filter structures supported by % DFILT/MFILT objects when FLAG is set to false. Omitting the % 'SystemObject', FLAG input pair is equivalent to setting the FLAG to % false (DSP System Toolbox required). % % % Example % h = fdesign.lowpass; % designoptions(h, 'equiripple') % % See also FDESIGN/DESIGNMETHODS and FDESIGN/VALIDSTRUCTURES. % Copyright 2006-2011 The MathWorks, Inc. % [EOF]
