Hello all, I need an advice with this code: function G=fotf(a,na,b,nb) if nargin==0, G.a=[]; G.na=[]; G.b=[]; G.nb=[]; G=class(G,'fotf'); elseif isa(a,'fotf'), G=a; elseif nargin==1 & isa(a,'double'), G=fotf(1,0,a,0); else, ii=find(abs(a)<eps); a(ii)=[]; na(ii)=[]; ii=find(abs(b)<eps); b(ii)=[]; nb(ii)=[]; G.a=a; G.na=na; G.b=b; G.nb=nb; G=class(G,'fotf'); end Syntax is : G=fotf(a,na,b,nb) its not my own this give an error : ??? Error using ==> class The CLASS function must be called from a class constructor. Error in ==> fotf at 9 G.a=a; G.na=na; G.b=b; G.nb=nb; G=class(G,'fotf'); Anyone know what is wrong will be a great help, thanks
